2019-01-28Input: pwm-vibra - stop regulator after disabling pwm, not beforePaweł Chmiel
This patch fixes order of disable calls in pwm_vibrator_stop. Currently when starting device, we first enable vcc regulator and then setup and enable pwm. When stopping, we should do this in oposite order, so first disable pwm and then disable regulator. Previously order was the same as in start.

Fix link error when TOUCHSCREEN_RASPBERRYPI_FW is enabled as a module and the dependent module is built-in. The 'depends on RASPBERRYPI_FIRMWARE' by itself prevents the touchscreen driver from being built-in when the firmware is configured as a module.

2019-01-13Input: mcs_touchkey - use struct_size() in kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

2019-01-04Input: soc_button_array - fix mapping of the 5th GPIO in a PNP0C40 deviceHans de Goede
The Microsoft documenation for the PNP0C40 device aka the "Windows-compatible button array" describes the 5th GpioInt listed in the resources as: '5. Interrupt corresponding to the "Rotation Lock" button, if supported'. Notice this describes the 5th entry as a button while we sofar have been mapping it to EV_SW, SW_ROTATE_LOCK. On my Point of View TAB P1006W-232 which actually comes with a rotation-lock button, the button indeed is a button and not a slider/switch. An image search for other Windows tablets has found 2 more models with a rotation-lock button and on both of those it too is a push-button and not a slider/switch. Further evidence can be found in the HUT extension HUTRR52 from Microsoft which adds rotation lock support to the HUT, which describes 2 different usages: "0xC9 System Display Rotation Lock Button" and "0xCA System Display Rotation Lock Slider Switch" note that switch is seen as a separate thing here and the non switch wording is an exact match for the "Windows-compatible button array" spec wording. TL;DR: our current mapping of the 5th GPIO to SW_ROTATE_LOCK is wrong because the 5th GPIO is for a push-button not a switch. This commit fixes this by maping the 5th GPIO to KEY_ROTATE_LOCK_TOGGLE.

2018-12-21auxdisplay: charlcd: fix x/y command parsingMans Rullgard
The x/y command parsing has been broken since commit 129957069e6a ("staging: panel: Fixed checkpatch warning about simple_strtoul()"). Commit b34050fadb86 ("auxdisplay: charlcd: Fix and clean up handling of x/y commands") fixed some problems by rewriting the parsing code, but also broke things further by removing the check for a complete command before attempting to parse it. As a result, parsing is terminated at the first x or y character. This reinstates the check for a final semicolon. Whereas the original code use strchr(), this is wasteful seeing as the semicolon is always at the end of the buffer. Thus check this character directly instead.

The match node are used as an identifier to compare against the current node, so we can directly drop the refcount after getting the node from the path as it is not used as pointer.

Commit ec0daae685b2 ("gpio: omap: Add level wakeup handling for omap4 based SoCs") attempted to fix omap4 GPIO wakeup handling as it was blocking deeper SoC idle states. However this caused a regression for GPIOs during runtime having over second long latencies for Ethernet GPIO interrupt as reportedy by Russell King <rmk+kernel@armlinux.org.uk>. Let's fix this issue by doing a partial revert of the breaking commit. We still want to keep the quirk handling around as it is also used for OMAP_GPIO_QUIRK_IDLE_REMOVE_TRIGGER. The real fix for omap4 GPIO wakeup handling involves fixes for omap_set_gpio_trigger() and omap_gpio_unmask_irq() and will be posted separately. And we must keep the wakeup bit enabled during runtime because of module doing clock autogating with autoidle configured.
