From 8a4b1870f8b2e5908536ffad4cea2ae943b9106c Mon Sep 17 00:00:00 2001 From: Sevinj Aghayeva Date: Sun, 3 Apr 2022 12:42:50 -0400 Subject: [PATCH] staging: r8188eu: simplify control flow The function iterates an index from 0 to NUM_PMKID_CACHE and returns the first index for which the condition is true. If no such index is found, the function returns -1. Current code has a complex control flow that obfuscates this simple task. Replace it with a loop. Also, given the shortened function body, replace the long variable name psecuritypriv with a short variable name p.
