The interrupt handler is setup in denali_init(), not in denali_drv_init(). This comment is false. Such a comment adds no value, so just delete it instead of move. Signed-off-by:

The struct member "idx" was used as an index for debug_array long ago, but the DEBUG_DENALI feature was removed by commit 7cfffac0 ("nand/denali: use dev_xx debug function to replace nand_dbg_print and some printk"). Since then, this has been only initialized, but never referenced. Signed-off-by:

For this driver, there is nothing between nand_scan_ident() and nand_scan_tail(). They can be merged into nand_scan(). Also, nand_scan() returns an appropriate error value when it fails. Use it instead of the fixed error code -ENXIO. Signed-off-by:

Since commit d1e1f4e4 ("mtd: nand: add support for reading ONFI parameters from NAND device"), the returned "type" is never used in nand_scan_ident(). Make nand_get_flash_type() simply return an integer value in order to avoid unnecessary ERR_PTR/PTR_ERR dance. Signed-off-by:

Drivers implementing ->cmd_ctrl() and relying on the default ->cmdfunc() implementation usually don't wait tCCS when a column change (RNDIN or RNDOUT) is requested. Add an option flag to ask the core to do so (note that we keep this as an opt-in to avoid breaking existing implementations), and make use of the ->data_interface information is available (otherwise, wait 500ns).

If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/mtd/nand/omap2_nand.ko | grep alias alias: platform:omap2-nand After this patch: $ modinfo drivers/mtd/nand/omap2_nand.ko | grep alias alias: platform:omap2-nand alias: of:N*T*Cti,omap2-nandC* alias: of:N*T*Cti,omap2-nand Signed-off-by:
