Input: wdt87xx_i2c - fix compiler warning

2025-01-22T18:40:00Z

As reported by the kernel test robot, the following warning occur: >> drivers/input/touchscreen/wdt87xx_i2c.c:1166:36: warning: 'wdt87xx_acpi_id' defined but not used [-Wunused-const-variable=] 1166 | static const struct acpi_device_id wdt87xx_acpi_id[] = { | ^~~~~~~~~~~~~~~ The 'wdt87xx_acpi_id' array is only used when CONFIG_ACPI is enabled. Wrapping its definition and 'MODULE_DEVICE_TABLE' in '#ifdef CONFIG_ACPI' prevents a compiler warning when ACPI is disabled.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Input: drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-13T22:43:19Z

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

Input: touchscreen - use sysfs_emit[_at]() instead of scnprintf()

2023-12-14T05:26:11Z

Follow the advice of the Documentation/filesystems/sysfs.rst and show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. Signed-off-by: ye xingchen Acked-by: Uwe Kleine-König Acked-by: Oliver Graute Signed-off-by: Dmitry Torokhov

Input: wdt87xx_i2c - use device core to create driver-specific device attributes

2023-09-06T21:29:04Z

Instead of creating driver-specific device attributes with devm_device_add_group() have device core do this by setting up dev_groups pointer in the driver structure.

Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

Input: wdt87xx_i2c - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:27Z

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.

Input: wdt87xx_i2c - Convert to i2c's .probe_new()

2022-12-02T22:53:47Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-266-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: wdt87xx_i2c - replace mdelay() with msleep() in wdt87xx_resume()

2018-07-27T18:59:05Z

wdt87xx_resume() is never called in atomic context. It calls mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep(). This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai Signed-off-by: Dmitry Torokhov

Input: remove unneeded MODULE_VERSION() usage in touchscreen drivers

2018-01-17T00:48:23Z

MODULE_VERSION is useless for in-kernel drivers, so just remove all usage of it in the touchscreen drivers. Along with this, some DRV_VERSION macros were removed as they are also pointless. Signed-off-by: Greg Kroah-Hartman Signed-off-by: Dmitry Torokhov
