Input: Use named initializers for arrays of i2c_device_data

2026-05-31T05:10:47+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

Input: stmfts - add optional reset GPIO support

2026-04-26T21:32:56+00:00

Add support for an optional "reset-gpios" property. If present, the driver drives the reset line high at probe time and releases it during power-on, after the regulators have been enabled.

Input: stmfts - disable regulators and disable irq when power on fails

2026-04-26T21:32:54+00:00

We must power off regulators and ensure that IRQ is disabled when failing at power on phase. Create stmfts_configure function to limit use of goto. Signed-off-by: David Heidelberg Link: https://patch.msgid.link/20260409-stmfts5-v4-5-64fe62027db5@ixit.cz Signed-off-by: Dmitry Torokhov

Input: stmfts - fix the MODULE_LICENSE() string

2026-04-26T21:32:52+00:00

Replace the bogus "GPL v2" with "GPL" as MODULE_LICNSE() string. The value does not declare the module's exact license, but only lets the module loader test whether the module is Free Software or not. See commit bf7fbeeae6db ("module: Cure the MODULE_LICENSE "GPL" vs. "GPL v2" bogosity") in the details of the issue. The fix is to use "GPL" for all modules under any variant of the GPL.
