As this is intentional behaviour, we should not return an error message, as we do today: =============== [ 0.000800] Failed to initialize '/bus@8000000/motherboard-bus@8000000/iofpga-bus@300000000/timer@120000': -22 =============== Replace the -EINVAL return with a debug message and return 0 instead. Also we do not reach the init function anymore if the DT node is disabled (as this is now handled by OF_DECLARE), so remove the explicit check for that case. This fixes a long standing bogus error when booting ARM's fastmodels.

This ensures that there is no memory leak, even in the case of a zoned disk changing type to a regular disk (e.g. with a reformat using the FORMAT WITH PRESET command or other vendor proprietary command). To do this, rename sd_zbc_clear_zone_info() to sd_zbc_free_zone_info() and remove sd_zbc_release_disk(). A call to sd_zbc_free_zone_info() is added to sd_zbc_read_zones() for drives for which sd_is_zoned() returns false. Furthermore, sd_zbc_free_zone_info() code make s sure that the sdkp rev_mutex is never used while not being initialized by gating the cleanup code with a a check on the zone_wp_update_buf field as it is never NULL when rev_mutex has been initialized.

This causes a NULL pointer dereference when sd_is_zoned() is called inside that function. Avoid this by removing the call to sd_zbc_release_disk() in sd_probe() error path. This change is safe and does not result in zone information memory leakage because the zone information for a zoned disk is allocated only when sd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set, resulting in sd_disk_release() being called when needed to cleanup a disk zone information using sd_zbc_release_disk().
