- u32 intr, doorbell;
+ u32 doorbell = 0, hwq_id = 0;
+ u32 intr;
Since hwq_id can be assigned the value -1, shouldn't its type be changed
from u32 into int, int16_t or int32_t?
+ struct ufs_hw_queue *hwq = NULL;
Is this pointer only used inside one branch of the if-statement below?
If so, can it be moved under "if (is_mcq_enabled(hba)) {"?
+ "%s: %s: tag: %u, DB: 0x%x, size: %d, IS: %u, LBA: %llu, opcode: 0x%x (%s), group_id: 0x%x, hqid: %d",
Consider changing "hqid" into "hwq_id" to make the trace information
easier to understand.
Thanks,
