| | * | pinctrl: samsung: Fix device node refcount leaks in Exynos wakeup controller ↵Krzysztof Kozlowski2019-10-011-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | init In exynos_eint_wkup_init() the for_each_child_of_node() loop is used with a break to find a matching child node. Although each iteration of for_each_child_of_node puts the previous node, but early exit from loop misses it. This leads to leak of device node.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return of exynos_eint_wkup_init() error path. Issue found with Coccinelle.

Since most of our pins do not exceed this value, we enable slewrate by default. Pins with a switching value that exceeds 50Mhz will have to explicitly disable slewrate. This patch changes the ABI. However, the slewrate macros are only used by SAM9X60 and, at this moment, there are no device-tree files available for this platform.

The PRCMU (power reset and control unit) knows which GPIO line offset fired an IRQ to wake the system up (if so desired) and this second IRQ was used to replay the action when the system came back online after suspend(). This is now known to be the wrong approach to solve this problem: in a patch series Lina Iyer has suggested to instead make it possible to model the IRQs as hierarchical with double parents. Also the current device trees do not contain the right information to make this code work, the latent IRQ is not specified nowadays giving noise like this in the console: [ 0.612168] gpio 8012e000.gpio: IRQ index 1 not found [ 0.622523] gpio 8012e080.gpio: IRQ index 1 not found Let's delete the latent IRQ code and reimplement it properly when we need it.
