Subject: [PATCH] mmc: core: make mmc_host_class constant
Date: Tue, 05 Mar 2024 16:49:30 -0300	[thread overview]
Message-ID: <20240305-class_cleanup-mmc-v1-1-4a66e7122ff3@marliere.net> (raw)

Since commit 43a7206b0963 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the mmc_host_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically
allocated at boot time.
