Upon failure during driver probe, the error code 1 is propagated back to the driver probe function which must return a negative value to indicate an error, but 1 is not negative, so the probe is considered to be successful even though it failed. Subsequently, removing the driver results in an oops because it is not in a valid state. This happens because none of the callers of ufshcd_init() expect a non-negative error code. Fix the return value and documentation to match actual usage.

Patch "Make HID attributes visible" is needed for older kernel versions
(e.g. 6.12) where ufs_get_device_desc() is called from ufshcd_probe_hba().
In these older kernel versions ufshcd_get_device_desc() may be called
after the sysfs attributes have been added. In the upstream kernel however
ufshcd_get_device_desc() is called before ufs_sysfs_add_nodes(). See also
the ufshcd_device_params_init() call from ufshcd_init(). Hence, calling

See also commit 69f5eb78d4b0 ("scsi: ufs: core: Move the
ufshcd_device_init(hba, true) call") in kernel v6.13.

 "Fixes only in drivers (ufs, mvsas, qla2xxx, target) that came in just
  before or during the merge window.

  The most important one is the qla2xxx which reverts a conversion to

  but which turned out on further testing to be causing data corruption"
