2015-11-25scsi: use sector_div instead of do_divArnd Bergmann1-2/+2
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.

2015-11-25hisi_sas: Remove dependency on of_irq_countJohn Garry3-40/+5
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.
