2023-11-24pinctrl: realtek: Fix logical error when finding descriptorTzuyi Chang1-2/+2
The pin descriptor should be returned if the name has been found in the descriptor table. Remove the negation in the if statement for accurate retrieval. Fixes: e99ce78030db ("pinctrl: realtek: Add common pinctrl driver for Realtek DHC RTD SoCs") Signed-off-by: Tzuyi Chang <tychang@realtek.com> Link: https://lore.kernel.org/r/20231121091107.5564-1-tychang@realtek.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2023-11-16pinctrl: lochnagar: Don't build on MIPSCharles Keepax1-1/+2
MIPS appears to define a RST symbol at a high level, which clashes with some register naming in the driver. Since there is currently no case for running this driver on MIPS devices simply cut off the build of this driver on MIPS.

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.
