scsi: message: fusion: Remove redundant variable iocnum
Variable iocnum is assigned a value that is never read, the assignment and hence the variable are redundant can be removed. Also update the comment to reflect the correct name of the variable being updated. Cleans up clang-scan warning: drivers/message/fusion/mptctl.c:641:8: warning: Although the value stored to 'iocnum' is used in the enclosing expression, the value is never actually read from 'iocnum' [deadcode.DeadStores] Link: https://lore.kernel.org/r/20220805113214.2339022-1-colin.i.king@gmail.com Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Martin K.
