From 36c6a7ac74044b8025488c018279115bb3c32eb0 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Mon, 21 Jul 2014 19:06:19 -0700 Subject: [PATCH] mtd: cfi_cmdset_0002: allow retry/timeout loop to exit The variable 'retries' is never modified, so if the reset operation never is going to complete, we'll get stuck in an infinite loop. It looks like the intention was to decrement 'retries' on every loop. Untested. Caught by Coverity.
