Replace bitfield struct hbm_cmd with simple u8 as we always access the value as whole. This allows us to remove few ugly type casts For possible further uses and documentation purposes we add corresponding bitmask defines Signed-off-by:

This fixes a type mismatch in the compression code where a size_t pointer was cast to a unsigned int pointer. On little endian archs, there is no issue. However on big endian archs, the value is incorrect, taking the high order bits and truncating the lower order bits. Signed-off-by:

The core must not modify available_scan_mask, because it causes problems with drivers where multiple instances of the driver share the same mask set. So make this explicit by marking available scan masks as const. The max1363 driver needs some minor adjustment to accommodate this change. Pull scan mask allocation into a separate function.

Prepare the driver for the addition of chip variants with a different number of channels. This is done by not hard-coding the number of channels, but instead add a field to the chip info struct holding the number of channels. Also do not embed the channel specs into the chip info, but rather store them independently. This allows sharing the same channel spec between different chip infos. Signed-off-by:

Use extended channel info attributes for the powerdown, powerdown_mode and powerdown_mode_available attributes. Note that this patch moves the chip info defintion around to avoid having to use forward declarations for the extended channel info attributes callbacks. Signed-off-by:

Sometimes devices have per channel properties which either do not map nicely to the current channel info scheme (e.g. string properties) or are very device specific, so it does not make sense to add generic support for them. Currently drivers define these attributes by hand for each channel. Depending on the number of channels this can amount to quite a few lines of boilerplate code. Especially if a driver supports multiple variations of a chip with different numbers of channels. In this case it becomes necessary to have a individual attribute list per chip variation and also a individual iio_info struct. This patch introduces a new scheme for handling such per channel attributes called extended channel info attributes. A extended channel info attribute consist of a name, a flag whether it is shared and read and write callbacks. The read and write callbacks are similar to the {read,write}_raw callbacks and take a IIO device and a channel as their first parameters, but instead of pre-parsed integer values they directly get passed the raw string value, which has been written to the sysfs file. It is possible to assign a list of extended channel info attributes to a channel. For each extended channel info attribute the IIO core will create a new sysfs attribute conforming to the IIO channel naming spec for the channels type, similar as for normal info attributes. Read and write access to this sysfs attribute will be redirected to the extended channel info attributes read and write callbacks. Signed-off-by: -

Use dev_pm_ops instead of legacy suspend/resume callbacks for IIO drivers. Note that this patch introduces a few new #ifdef CONFIG_PM_SLEEP around the suspend and resume callbacks to avoid warnings of unused functions if CONFIG_PM_SLEEP is not defined. Signed-off-by:

Lifted from proposal for in kernel interface built on the out of staging branch. Two elements here: * Map as defined in "inkern.h" * Matching code to actually get the iio_dev and channel that we want from the global list of IIO devices. V4: Everything now built if iio is built (rather than being optional) Removal race condition prevented by using info pointer as a check of removal under a lock. V3: Drop the option of registering / getting channels using dev pointer. Stick to name only as suggested by Mark Brown (this has caused user confusion in the regulator framework.) V2: As per Greg KH suggestion, move over to registration by passing the tables into the provider drivers (how regulator does it). This does not prevent us using the original more flexible approach if at a later date there is a usecase that demands it. Signed-off-by: -

This prevents use of provider callbacks after it has been unregistered. Note that all code using this that can be called from a consumer *must* check the pointer before using and hold the info_exist_lock throughout the usage of the callbacks in info. Signed-off-by:

In order to detect WDT feature on the dsp code, we need to find the symbol used to enable it inside the baseimage. This should fix the warning comming from L3 driver: WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:161 omap3_l3_app_irq... In-band Error seen by IVA_SS at address 0 ...

In order to detect it at runtime, we need the code handling wdt clock available at runtime to decide whether to enable or disable based on the baseimage symbols. Default timeout has been set to 5 seconds. Downside is that we will lose the option to set a custom timeout for overflow, but than can be added (if needed) as part of debugfs. Signed-off-by:

p80211item_pstr6_t is the size of "msg1.bssid" (16 bytes) but msg1.bssid.data is type p80211pstr6_t and it is smaller (7 bytes). We had just set that memory to zeroes earlier and now we're writing over it with 0xff because we're writing past the end of the struct. I don't know if this actually causes a problem. It may be that we initialize the extra 0xff bytes correctly later. But the current code is obviously wrong and we should fix it. Signed-off-by:

Commit 9256a478 fixed a deadlock condition, being sure that the buddy list spinlock is always taken before the page spinlock. However in zbud_free_and_delist() locking order is the opposite (page lock -> list lock). Possible unsafe locking scenario (reported by lockdep): CPU0 CPU1 ---- ---- lock(&(&zbpg->lock)->rlock); lock(zbud_budlists_spinlock); lock(&(&zbpg->lock)->rlock); lock(zbud_budlists_spinlock); Fix by grabbing the locks in opposite order in zbud_free_and_delist().

netif_rx is meant to be called from interrupts because it doesn't wake up ksoftirqd. For calling from outside interrupts, netif_rx_ni exists. This stops the error "NOHZ: local_softirq_panding 08" that happens on some machines with NOHZ and plip --- it is caused by the fact that softirq is pending and ksoftirqd is sleeping. Signed-off-by:

Ramster can't be a module (yet) and depends on CONFIGFS_FS=y, but allmodconfig builds with CONFIGFS_FS=m, which breaks the build. And forcing CONFIGFS_FS=y with select breaks the build in other ways.
