From 6b7a783ebd2181aa2e0e6f9f5509da8466e321e3 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Sat, 21 Feb 2015 15:15:16 +1100 Subject: [PATCH] mmc: pwrseq_simple: fix error path in mmc_pwrseq_simple_alloc The current error-path code (when gpiod_get_index() reports an error) can never free pwrseq->reset_gpios[0], but might try to tree pwrseq->reset_gpios[-1], which has unfortunate consequences.
