[PATCH v2 16/20] mtd: sst25l: Warn about failure to unregister mtd device

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

When an spi driver's remove function returns a non-zero error code
nothing happens apart from emitting a generic error message. Make this
error message more device specific and return zero instead.
