Prasant Jalan 4895398d03 staging: sm750fb: fixing function return with lock held
lynxfb_suspend() & lynxfb_resume() return on errors while holding
console_lock.

Adding 'goto' such that proper cleanups can be done before returning
from function and therefore console_lock can be released before
returning.

Arnd Bergmann 52d0744d75 staging: sm750fb: prefix global identifiers
Renaming some symbols inside this driver caused a conflict with
an existing function, which in turn results in a link error:

drivers/staging/sm750fb/sm750fb.o: In function `enable_dma':
ddk750_hwi2c.c:(.text.enable_dma+0x0): multiple definition of `enable_dma'

This adds a sm750_ prefix to each global symbol in the sm750fb
driver that does not already have one. I manually looked for the
symbols and then converted the driver using

for i in calc_pll_value format_pll_reg set_power_mode set_current_gate    \
