Since all pointers passed to the srb_t.done() and srb_t.free() functions have type srb_t, change the type of the first argument of these functions from void * into struct srb *. This allows the compiler to verify the argument types for these functions. This patch does not change any functionality. Cc: Himanshu Madhani <hmadhani@marvell.com> Signed-off-by:

This change makes it easier to detect qla24xx_read_flash_data() failures and also to handle such failures. This change does not modify the behavior of the driver since all callers ignore the qla24xx_read_flash_data() return value. Cc: Himanshu Madhani <hmadhani@marvell.com> Signed-off-by:

Introduce the be_id_t and le_id_t data types for Fibre Channel source and destination ID formats supported by the firmware instead of using an uint8_t[3] array. Introduce functions for converting from and to the port_id_t data types. This patch does not change the behavior of the qla2xxx driver but improves source code readability and also allows the compiler to verify the endianness of Fibre Channel IDs.

Such a timeout is a severe issue. Hence complain if waiting for pending commands times out. This patch fixes a small bug: it modifies qla82xx_chip_reset_cleanup() such that the "Done waiting" message is reported if qla82xx_chip_reset_cleanup() succeeded instead of if that function failed.

Since qlt_remove_target() only calls qlt_release() if vha->vha_tgt.qla_tgt != NULL, checking that pointer inside qlt_release() is not necessary.
