Instead of returning an error code in alua_check_tpgs() we should rather return the tpgs mode directly and have a cleaner syntax. Signed-off-by:

The only check for a valid sense code is calling scsi_normalize_sense() and check the return value. So drop the pointless checks and rely on scsi_normalize_sense() to figure out if the sense code is valid. With that we can also remove the 'senselen' field. Signed-off-by:

Non-disk devices might support ALUA, but the firmware implementation is untested and frequently broken. As we're don't actually need it disable ALUA support for non-disk device for now. Signed-off-by:

device handler initialisation might fail due to a number of reasons. But as device_handlers are optional this shouldn't cause us to disable the device entirely. So just ignore errors from scsi_dh_add_device(). Reviewed-by:

As scsi_dh.c is now always compiled in we should be moving the 'dh_state' attribute to the generic code. Reviewed-by:

Fix a smatch warning: drivers/scsi/mvsas/mv_sas.c:740 mvs_task_prep() warn: curly braces intended? The code is correct, the indention is misleading. When the device is not ready we want to return SAS_PHY_DOWN. But current indentation makes it look like we only do so in the else branch of if (mvi_dev). Signed-off-by:

do_div is the wrong way to divide a sector_t, as it is less efficient when sector_t is 32-bit wide. With the upcoming do_div optimizations, the kernel starts warning about this: drivers/scsi/scsi_debug.c: In function 'dif_store': include/asm-generic/div64.h:207:28: warning: comparison of distinct pointer types lacks a cast This changes the code to use sector_div instead, which always produces optimal code.

Originally the driver would use of_irq_count to calculate how much memory is required for storing the interrupt names, since the number of interrupt sources for the controller is variable. Since of_irq_count cannot be used by the driver, use fixed names. Signed-off-by:
