From 74711d1ea1956f9fed323cc8c38981573b99ffb7 Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Thu, 7 Jan 2021 07:47:30 +0000 Subject: [PATCH] spi: atmel-quadspi: Disable clock in probe error path stable inclusion from stable-5.10.4 commit e7351d8c7804be475762673d8dd0f46f550c354c bugzilla: 46903 -------------------------------- commit 0e685017c7ba1a2fe9f6f1e7a9302890747d934c upstream. If the call to of_device_get_match_data() fails on probe of the Atmel QuadSPI driver, the clock "aq->pclk" is erroneously not unprepared and disabled. Fix it.
