Next: [PATCH] backlight: lcd: Add Epson L4F00242T03 LCD driver.
From: Phil Carmody on 18 Dec 2009 08:40 Many struct driver_attribute descriptors are purely read-only structures, and there's no need to change them. Therefore make the promise not to, which will let those descriptors be put in a ro section.
