From: Sevinj Aghayeva Date: Sun, 3 Apr 2022 16:53:25 +0000 (-0400) Subject: staging: rtl8712: simplify control flow X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9f2d13a65d1aca945cfc6845cb100ceab33ddb0d;p=linux.git staging: rtl8712: 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.
