This patch does following improvements to sbi_fifo: 1. Use valid SBI_Exxxx error codes instead of -1 2. The sbi_fifo_is_full() and sbi_fifo_is_empty() did not acquire qlock before accessing head and tail hence fixed it 3. Added avail member for ease in debugging and simplifying head/tail updates. Due to above changes size of sbi_fifo changes from 48 bytes to 56 bytes. Signed-off-by: Anup Patel <anup.patel@wdc.com>
