[PATCH 2/2] ARM: mx5/mx53_evk: Remove unneeded gpio_set_value call

I guess that the !GPIOLIB issue is related to a configuration option, that
can't very easily be detected from looking at the C file alone?
Ignoring that issue, the following semantic patch addresses the common
case where there is no error checking for the input or output call, but
there may be error checking for the gpio_request call. This transforms
over 500 occurrences.
These rules also require that the first argument to gpio_request should
not be used at all before the direction call. This may be too
conservative. For example there are some intervening references in
drivers/staging/olpc_dcon/olpc_dcon_xo_1.c
in calls to cs5535_gpio_clear and cs5535_gpio_isset.
