Subject: [PATCH] spi: atmel-quadspi: fix crash while suspending
Date: Wed, 24 Apr 2019 09:17:59 +0000 [thread overview]
Message-ID: <1556097463-29672-1-git-send-email-claudiu.beznea@microchip.com> (raw)
From: Claudiu Beznea <claudiu.beznea@microchip.com>
atmel_qspi objects are kept in spi_controller objects, so, first get
pointer to spi_controller object and then get atmel_qspi object from
spi_controller object.
Fixes: 2d30ac5ed633 ("mtd: spi-nor: atmel-quadspi: Use spi-mem interface for atmel-quadspi driver")
