Hi all, While booting the latest kernel (from linux-omap) on omap3evm, I came across this error. [ 3.202575] ads7846 spi1.0: unable to get regulator: -19 [ 3.208190] ------------[ cut here ]------------ [ 3.212890] WARNING: at drivers/gpio/gpiolib.c:1258 gpio_free+0x114/0x140() [ 3.219940] Modules linked in: [ 3.223083] [<c004e57c>] (unwind_backtrace+0x0/0xec) from [<c007e5d8>] (warn_slowpath_common+0x4c/0x64) ... ... [ 3.342529] ---[ end trace 1b75b31a2719ed1f ]--- In drivers/input/touchscreen/ads7846.c, we attempt to get the regulator as: ts->reg = regulator_get(&spi->dev, "vcc"); This regulator isn't defined for omap3evm. And I suspect - once defined - the name will be different than "vcc". Looking at pointers on how this should be handled.
