This patch makes a number of changes with respect to the error-handling code: * Remove cleanup calls for the devm functions in both the error handling code and the remove function. This cleanup is done automatically. * The previous change simplifies the cleanup code at the end of the function such that there is nothing to do on the failure of the call to devm_ioremap. So it is changed to just return directly. * There is no need for the ifs in the cleanup code at the end of the function, because in each case the cleanup needed is statically known. Drop the ifs, add new err labels, and drop the initializations of the tested variables to NULL. * Change the call to request_irq to a call to devm_request_irq, so that it is cleaned up on exit. * Cause the return value of devm_request_irq to go into the returned variable rv rather than the unused variable ret. Drop ret. Signed-off-by:
