LABBE Corentin	56880a243c	gpio: 74xx: fix a possible NULL dereference ... of_match_device could return NULL, and so cause a NULL pointer dereference later at line 132: priv->flags = (uintptr_t) of_id->data; Reported-by: coverity (CID 1324141) Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>	2015-11-17 14:39:17 +01:00
Nicholas Krause	54442658d8	gpio: 74xx: Fix build warning about void to integer cast ... This fixes the build warning , warning: cast from pointer to integer of different size when building this file on a x86 allmodconfig configuration. In order for me to fix this build warning I changed the cast in the function mmio_74xx_gpio_probe from casting the variable data of the stucture pointer of_id to uintptr_t rather then unsigned when assigning to the variable flag of the structure pointer priv of the structure type mmio_74xx_gpio_priv.
