Subject: [PATCH] staging: rtl8723bs: hal: remove redundant variable n
Git-commit: b33f56a1e40588214320926293585f088fb390b0
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430

The variable n is being assigned a value that is never read inside
an if statement block, the assignment is redundant and can be removed.
With this removed, n is only being used for a constant loop bounds
check, so replace n with that value instead and remove n completely.

Addresses-coverity: ("Unused value")
