Subject: [PATCH v2 1/4] dev_printk: add new dev_err_probe() helpers
Date: Tue, 23 Apr 2024 17:20:30 +0200 [thread overview]
Message-ID: <20240423-dev-add_dev_errp_probe-v2-1-12f43c5d8b0d@analog.com> (raw)
In-Reply-To: <20240423-dev-add_dev_errp_probe-v2-0-12f43c5d8b0d@analog.com>
From: Nuno Sa <nuno.sa@analog.com>
This is similar to dev_err_probe() but for cases where an ERR_PTR() or
ERR_CAST() is to be returned simplifying patterns like:
dev_err_probe(dev, ret, ...);
return ERR_PTR(ret)
or
dev_err_probe(dev, PTR_ERR(ptr), ...);
return ERR_CAST(ptr)
