From 329c6cf32f513c1c6cefb7f9551b56f8e40279a8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20Miros=C5=82aw?= Date: Thu, 2 Jan 2020 11:42:16 +0100 Subject: [PATCH] mmc: sdhci-of-at91: fix memleak on clk_get failure MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit a04184ce777b46e92c2b3c93c6dcb2754cb005e1 ] sdhci_alloc_host() does its work not using managed infrastructure, so needs explicit free on error path. Add it where needed.
