2022-02-09	spi: make remove callback a void function	Uwe Kleine-König	1	-2/+1
	The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2021-08-13	drm/panel: s6d27a1: Add driver for Samsung S6D27A1 display panel	Markuss Broks	1	-0/+320
	This adds a driver for Samsung S6D27A1 display controller and panel. This panel is found in the Samsung GT-I8160 mobile phone, and possibly some other mobile phones. This display needs manufacturer commands to configure it; the commands used in this driver were taken from downstream driver by Gareth Phillips; sadly, there is almost no documentation on what they actually do. This driver re-uses the DBI infrastructure to communicate with the display. This driver is heavily based on WideChips WS2401 display controller driver by Linus Walleij and on other panel drivers for reference.
