[PATCH] drm/armada: Use the correct prototype for a struct file_operations .write function

[PATCH] drm/armada: Use the correct prototype for a struct file_operations .write function

[Christophe JAILLET]

.write functions from struct file_operations return a ssize_t not an int.

This is maybe not an issue for architectures that use this driver, but it
is nicer to explicitly use the correct return type.
