Subject: [PATCH v2 1/2] devres: Switch to use dev_err_probe() for unification
Date: Thu, 29 Feb 2024 17:53:39 +0200	[thread overview]
Message-ID: <20240229155507.3853059-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240229155507.3853059-1-andriy.shevchenko@linux.intel.com>

The devm_*() APIs are supposed to be called during the ->probe() stage.
Many drivers (especially new ones) have switched to use dev_err_probe()
for error messaging for the sake of unification. Let's do the same in
the devres APIs.
