megaraid_sas: add missing curly braces in ioctl handler
[ Upstream commit 3deb9438d34a09f6796639b652a01d110aca9f75 ]
gcc-6 found a dubious indentation in the megasas_mgmt_fw_ioctl
function:
drivers/scsi/megaraid/megaraid_sas_base.c: In function 'megasas_mgmt_fw_ioctl':
drivers/scsi/megaraid/megaraid_sas_base.c:6658:4: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
kbuff_arr[i] = NULL;
^~~~~~~~~
drivers/scsi/megaraid/megaraid_sas_base.c:6653:3: note: ...this 'if' clause, but it is not
if (kbuff_arr[i])
^~
The code is actually correct, as there is no downside in clearing a NULL
pointer again.
This clarifies the code and avoids the warning by adding extra curly
braces.
