scsi: mpt3sas: Fix loop logic
The retry loop continues to iterate until the count reaches 30, even after receiving the correct value. Exit loop when a non-zero value is read. Fixes: 4ca10f3e3174 ("scsi: mpt3sas: Perform additional retries if doorbell read returns 0") Cc: stable@vger.kernel.org Signed-off-by: Ranjan Kumar <ranjan.kumar@broadcom.com> Link: https://lore.kernel.org/r/20231020105849.6350-1-ranjan.kumar@broadcom.com Signed-off-by: Martin K.
