fixes following Smatch static check warning: ./drivers/pinctrl/sunxi/pinctrl-sunxi.c:1112 sunxi_pinctrl_build_state() warn: passing devm_ allocated variable to kfree. 'pctrl->functions' As we will be calling krealloc() on pointer 'pctrl->functions', which means kfree() will be called in there, devm_kzalloc() shouldn't be used with the allocation in the first place. Fix the warning by calling kcalloc() and managing the free procedure in error path on our own. Fixes: 0e37f88d ("ARM: sunxi: Add pinctrl driver for Allwinner SoCs") Signed-off-by:

We now using a common macro for PM operations in pin control drivers for Intel SoCs, and since that macro relies on the definition and macro from linux/pm.h header file, it's logical to include it directly in pinctrl-intel.h. Otherwise it's a bit fragile and requires a proper ordering of header inclusion in C files. Signed-off-by:

Almost all MediaTek SoCs apply the exact same logic to build eint, so move the common functions into pinctrl-mtk-common-v2.c to allow each new pinctrl driver to reuse them. Also, add a protection checker on hw->soc->eint_hw to avoid invalid memory access when there's certain SoC not to define its eint_hw properly in the code flow. Signed-off-by:

Zhiyong Tao authored
Add pinctrl-paris core that implements vendor dt-binding which MediaTek tablet, box and smartphone-based SoCs such as MT81xx, MT27xx, and MT67xx SoCs really want to depend on. The driver is just completely rewritten according to pinctrl-mtk-common.c but uses the new logic from pinctrl-mtk-common-v2.c to have an elegant way to support new SoCs in the future. Signed-off-by:

Sean Wang authored
Because the pincrl-mtk-common.c is an implementation for per-pin binding, its pin descriptor includes more information than pinctrl-mtk-common-v2 so far can support. So, we complement these data before writing a driver using pincrl-mtk-common-v2.c for per-pin binding. By the way, the size of struct mtk_pin_desc would be larger than struct pinctrl_pin_desc can hold, so it's necessary to have a copy before the pins information is being registered into the core.
