* | drivers/iio/adc/at91_adc.c: use devm_ functionsJulia Lawall2012-08-161-34/+8
|/ | | | | | | | | | | | | | | | | | 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. The call to platform_get_resource(pdev, IORESOURCE_MEM, 0) is moved coser to the call to devm_request_and_ioremap, which is th first use of the result of platform_get_resource. This does not use devm_request_irq to ensure that free_irq is executed before its idev argument is freed.
