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:

This patch adds the initial bare main driver for the HiSilicon SAS HBA. This only introduces the changes to build and load the main driver module. The complete driver consists of the core main module and also a module platform driver for driving the hw. The HBA is a platform device. Signed-off-by:

Call _init_tables before chip-specific initialization. This avoids code duplication and fixes a bug(?) in 880 init where the values read from flash into atpdev->sp are then overwritten by calling init_tables. Signed-off-by:
