2025-03-25objtool, Input: cyapa - Remove undefined behavior in cyapa_update_fw_store()Josh Poimboeuf
In cyapa_update_fw_store(), if 'count' is zero, the write to fw_name[count-1] underflows the array. Presumably that's not possible in normal operation, as its caller sysfs_kf_write() already checks for zero. Regardless it's a good idea to check for the error explicitly and avoid undefined behavior.

2025-01-20Input: synaptics - fix crash when enabling pass-through portDmitry Torokhov
When enabling a pass-through port an interrupt might come before psmouse driver binds to the pass-through port. However synaptics sub-driver tries to access psmouse instance presumably associated with the pass-through port to figure out if only 1 byte of response or entire protocol packet needs to be forwarded to the pass-through port and may crash if psmouse instance has not been attached to the port yet. Fix the crash by introducing open() and close() methods for the port and check if the port is open before trying to access psmouse instance. Because psmouse calls serio_open() only after attaching psmouse instance to serio port instance this prevents the potential crash. Reported-by: Takashi Iwai <tiwai@suse.de> Fixes: 100e16959c3c ("Input: libps2 - attach ps2dev instances as serio port's drvdata") Link: https://bugzilla.suse.com/show_bug.cgi?id=1219522 Cc: stable@vger.kernel.org Reviewed-by: Takashi Iwai <tiwai@suse.de> Link: https://lore.kernel.org/r/Z4qSHORvPn7EU2j1@google.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2025-01-14Input: Use str_enable_disable-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

2024-10-15Input: switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/input/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in a few drivers.

2024-08-29Input: cypress_ps2 - fix waiting for command responseDmitry Torokhov
Commit 8bccf667f62a ("Input: cypress_ps2 - report timeouts when reading command status") uncovered an existing problem with cypress_ps2 driver: it tries waiting on a PS/2 device waitqueue without using the rest of libps2. Unfortunately without it nobody signals wakeup for the waiting process, and each "extended" command was timing out. But the rest of the code simply did not notice it. Fix this by switching from homegrown way of sending request to get command response and reading it to standard ps2_command() which does the right thing.

2024-07-03Input: cypress_ps2 - use u8 when dealing with byte dataDmitry Torokhov
When dealing with byte data use u8 instead of unsigned char or int. Stop layering error handling in cypress_ps2_sendbyte() and simply pass on error code from ps2_sendbyte(). Additionally use u8 instead of unisgned char throughout the code.

2024-07-03Input: cypress_ps2 - propagate errors from lower layersDmitry Torokhov
Do not override errors reported by lower layers with generic "-1", but propagate them to the callers. Change the checks for errors to be in the form of "if (error)" to maintain consistency.

2024-07-03Input: cypress_ps2 - fix error handling when sending command failsDmitry Torokhov
Stop layering error handling in cypress_ps2_sendbyte() and simply pass on error code from ps2_sendbyte() and use it in the callers. This fixes mishandling of error condition in cypress_ps2_read_cmd_status() which expects errors to be negative.

2024-07-03Input: cypress_ps2 - clean up setting reporting rateDmitry Torokhov
Casting an integer field containing desired rate to a pointer to bytes works on little endian architectures where the driver is used, but not a good practice. Use a temporary of proper type instead.

2024-06-02Input: mouse - use sizeof(*pointer) instead of sizeof(type)Erick Archer
It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). This patch has no effect on runtime behavior.

2024-05-28Input: elantech - fix touchpad state on resume for Lenovo N24Jonathan Denose
The Lenovo N24 on resume becomes stuck in a state where it sends incorrect packets, causing elantech_packet_check_v4 to fail. The only way for the device to resume sending the correct packets is for it to be disabled and then re-enabled. This change adds a dmi check to trigger this behavior on resume.

2024-05-13Input: drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
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.
