spi: atmel-quadspi: fix crash while suspending (e5c27498) · Commits · 戴 / test

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: ("mtd: spi-nor: atmel-quadspi: Use spi-mem interface for atmel-quadspi driver") Signed-off-by:
