3.19.8-ckt18 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> commit 3deb9438d34a09f6796639b652a01d110aca9f75 upstream. 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.
