Subject: mtd: devices: m25p80: Use spi_mem_set_drvdata() instead of
spi_set_drvdata()
Git-commit: 1e07392e7b147fd15082f9b755fc249e853f9b96
Patch-mainline: v4.18-rc1
References: fate#326572
SPI mem drivers should use spi_mem_set_drvdata() not spi_set_drvdata()
to store their private data. Using spi_set_drvdata() will mess the
spi -> spi-mem link up and cause a kernel panic at shutdown or
device removal time.
Fixes: 4120f8d158ef ("mtd: spi-nor: Use the spi_mem_xx() API")
