[media] qt1010: Reduce text size by using static const · efc0ac5a

Mauro Carvalho Chehab authored Apr 28, 2015



Using static const allows the compiler to optimize the code.

Before static const:
   text	   data	    bss	    dec	    hex	filename
   4982	    524	   1568	   7074	   1ba2	drivers/media/tuners/qt1010.o

After static const:
   text	   data	    bss	    dec	    hex	filename
   4714	    524	   1568	   6806	   1a96	drivers/media/tuners/qt1010.o

[media] ir-sony-decoder: shutup smatch warnings · abefe12a

Mauro Carvalho Chehab authored Apr 28, 2015

There are some false-positive warnings produced by smatch:
drivers/media/rc/ir-sony-decoder.c:129 ir_sony_decode() warn: missing break? reassigning 'data->state'
drivers/media/rc/ir-sony-decoder.c:137 ir_sony_decode() warn: missing break? reassigning 'data->state'
drivers/media/rc/ir-sony-decoder.c:165 ir_sony_decode() warn: missing break? reassigning 'data->state'

This is due to the logic used there to detect the need of a break.

While those are false positives, it is easy to get rid of them without
any drawbacks. The side effect is a cleaner function, with is good.

[media] saa717x: fix multi-byte read code · 4c7ba408

Mauro Carvalho Chehab authored Apr 28, 2015



As reported by smatch:
	drivers/media/i2c/saa717x.c:155 saa717x_read() warn: mask and shift to zero
	drivers/media/i2c/saa717x.c:155 saa717x_read() warn: mask and shift to zero

This is done right at saa717x_write(), but the read function is
broken. Thankfully, there's just one place at saa717x driver that
uses multibyte read (for status report, via printk).

Yet, let's fix it. From saa717x_write(), it is clear that the
bytes are in little endian:
		mm1[4] = (value >> 16) & 0xff;
		mm1[3] = (value >> 8) & 0xff;
		mm1[2] = value & 0xff;

So, the same order should be valid for read too.

Compile-tested only.

[media] v4l: of: Parse variable length properties --- link-frequencies · 698da18e

Sakari Ailus authored Mar 22, 2015

The link-frequencies property is a variable length array of link frequencies
in an endpoint. The array is needed by an increasing number of drivers, so
it makes sense to add it to struct v4l2_of_endpoint.

However, the length of the array is variable and the size of struct
v4l2_of_endpoint is fixed since it is allocated by the caller. The options
here are

1. to define a fixed maximum limit of link frequencies that has to be the
global maximum of all boards. This is seen as problematic since the maximum
could be largish, and everyone hitting the problem would need to submit a
patch to fix it, or

2. parse the property in every driver. This doesn't sound appealing as two
of the three implementations submitted to linux-media were wrong, and one of
them was even merged before this was noticed, or

3. change the interface so that allocating and releasing memory according to
the size of the array is possible. This is what the patch does.

v4l2_of_alloc_parse_endpoint() is just like v4l2_of_parse_endpoint(), but it
will allocate the memory resources needed to store struct v4l2_of_endpoint
and the additional arrays pointed to by this struct. A corresponding release
function v4l2_of_free_endpoint() is provided to release the memory allocated
by v4l2_of_alloc_parse_endpoint().

In addition to this, the link-frequencies property is parsed as well, and
the result is stored to struct v4l2_of_endpoint field link_frequencies.

[media] v4l: of: Instead of zeroing bus_type and bus field separately, unify this · 161aadae

Sakari Ailus authored Mar 22, 2015



Zero the entire struct starting from bus_type. As more fields are added, no
changes will be needed in the function to reset their value explicitly.

x86_64, asm: Work around AMD SYSRET SS descriptor attribute issue · 61f01dd9

Andy Lutomirski authored Apr 26, 2015

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with
SS == 0 results in an invalid usermode state in which SS is apparently
equal to __USER_DS but causes #SS if used.

Work around the issue by setting SS to __KERNEL_DS __switch_to, thus
ensuring that SYSRET never happens with SS set to NULL.

This was exposed by a recent vDSO cleanup.
