Subject: scsi: pm8001: Replace one-element array with flexible-array member
Git-commit: fd2f045202d12c55748090885c47cc5f9a6c3c72
Patch-mainline: v6.1-rc1
References: jsc#PED-1559
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct fw_control_info.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines
on memcpy() and help us make progress towards globally enabling
-fstrict-flex-arrays=3 [1].
