Subject[PATCH v3 07/27] Input: bu21013_ts - Simplify with dev_err_probe()
Date
Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and also it prints the error value.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
Reviewed-by: Hans de Goede <hdegoede@redhat.com>

Changes since v1:
1. Remove unneeded PTR_ERR_OR_ZERO, as pointed by Andy.
