Thanks for the feedback. I can also check that there is no call to
gpio_request or either of the direction functions between the call to
gpio_request and the call to the direction function to transform. The
semantic patch and the result for the case where there is no error
handling on the direction function are below.
On the other hand, the constraint that everything should be requested
before initialization is not always respected, eg:
arch/arm/mach-mx3/mx31moboard-smartbot.c
Perhaps code like this should be changed to move up the requests?
