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.

2023-10-07pinctrl: realtek: Fix some NULL dereference warningsLinus Walleij1-1/+9
Just inspecting the code doesn't convince me that this is a real issue, but the tools complain that it is so I will just handle it.

2023-10-07pinctrl: realtek: Tag unused pins as __maybe_unusedLinus Walleij2-2/+4
These pin definitions are helpful to have when working with the driver in the future, so they are in a sense a bit like documentation. They could be commented out as well, but why. This should fix these build warnings: drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_boot_sel_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_reset_n_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_scan_switch_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_testmode_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_wd_rset_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_boot_sel_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_reset_n_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_scan_switch_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_testmode_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_wd_rset_pins' defined but not used [-Wunused-const-variable=] Cc: Tzuyi Chang <tychang@realtek.com> Link: https://lore.kernel.org/oe-kbuild-all/202309270313.mBEc9o1A-lkp@intel.com/ Link: https://lore.kernel.org/oe-kbuild-all/202309270448.7Aen3Sgx-lkp@intel.com/ Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Link: https://lore.kernel.org/r/20231006-fix-realtek-warnings-v1-1-09af253312ba@linaro.org
2023-10-07pinctrl: realtek: Fix error handling in probe()Dan Carpenter1-5/+13
There are several issues in the probe function: 1) of_iomap() return NULL on error but the code checks for error pointers. 2) pinctrl_register() is the reverse. It returns error pointers but the code checks for NULL. 3) The error paths need to call iounmap(data->base) before returning to avoid a resource leak.
