Series [1/1] media: mc-device.c: use DEVICE_ATTR_RO() helper macro | expand

Commit Message

Leizhen (ThunderTown) June 3, 2021, 7:12 a.m. UTC 
Use DEVICE_ATTR_RO() helper macro instead of DEVICE_ATTR(), which is
simpler and more readable.

Due to the name of the read function of the sysfs attribute is normalized,
there is a natural association.
