2023-11-15pinctrl: avoid reload of p state in list iterationMaria Yu1-3/+3
When in the list_for_each_entry iteration, reload of p->state->settings with a local setting from old_state will turn the list iteration into an infinite loop. The typical symptom when the issue happens, will be a printk message like: "not freeing pin xx (xxx) as part of deactivating group xxx - it is already used for some other setting". This is a compiler-dependent problem, one instance occurred using Clang version 10.0 on the arm64 architecture with linux version 4.19.

2023-11-14pinctrl: s32cc: Avoid possible string truncationChester Lin1-2/+2
With "W=1" and "-Wformat-truncation" build options, the kernel test robot found a possible string truncation warning in pinctrl-s32cc.c, which uses an 8-byte char array to hold a memory region name "map%u". Since the maximum number of digits that a u32 value can present is 10, and the "map" string occupies 3 bytes with a termination '\0', which means the rest 4 bytes cannot fully present the integer "X" that exceeds 4 digits. Here we check if the number >= 10000, which is the lowest value that contains more than 4 digits.
