Subject: [PATCH v3 5/9] nvmem: remove unneeded __nvmem_device_put()
Date: Wed, 29 Apr 2026 17:43:20 +0200	[thread overview]
Message-ID: <20260429-nvmem-unbind-v3-5-2a694f95395b@oss.qualcomm.com> (raw)
In-Reply-To: <20260429-nvmem-unbind-v3-0-2a694f95395b@oss.qualcomm.com>

__nvmem_device_put() is wrapped by nvmem_device_put() but there's no
extra functionality offered by the latter so just fold one into the
other. There's still the corresponding __nvmem_device_get() so in order
to keep things symmetrical: rename it to nvmem_device_match() to better
reflect its functionality and not confuse users by its presence in the
absence of the similarly prefixed put() counterpart.
