[PATCH 5.19 0604/1157] mtd: st_spi_fsm: Disable clock only after device was unregistered

[Greg Kroah-Hartman]

From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>

[ Upstream commit cd043c613e21bb6f039057043da759471706adf5 ]

Until mtd_device_unregister() returns the device is expected to be
operational. So only disable the clock after the mtd is unregistered.

Fixes: 1fefc8ecb834 ("mtd: st_spi_fsm: add missing clk_disable_unprepare() in stfsm_remove()")
