Subject: [PATCH] io_uring: remove redundant assignment to ret in
 io_register_iowq_max_workers()
Git-commit: 83956c86fffe0465408c7d62e925d88748075e00
Patch-mainline: v5.16-rc1
References: bsc#1205205

After the assignment, only exit path with label 'err' uses ret as
return value. However,before exiting through this path with label 'err',
ret is assigned with the return value of io_wq_max_workers(). Hence, the
initial assignment is redundant and can be removed.
