b5d4190f7e fbdev: jz4740: Use devm_request_and_ioremap
Use devm_request_and_ioremap instead of request_mem_region + devm_ioremap.

This also fixes the following compile error introduced in commit b2ca7f4d
("drivers/video/jz4740_fb.c: use devm_ functions"):

drivers/video/jz4740_fb.c: In function 'jzfb_probe':
	drivers/video/jz4740_fb.c:676:2: error: implicit declaration of function 'devm_ioremap'
	drivers/video/jz4740_fb.c:676:13: warning: assignment makes pointer from integer without a cast

b2ca7f4d74 drivers/video/jz4740_fb.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in the
probe function of a platform device and is only freed in the remove function.

ac751efa6a console: rename acquire/release_console_sem() to console_lock/unlock()
The -rt patches change the console_semaphore to console_mutex.  As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.
