Pull input layer fixes from Dmitry Torokhov: - a change to the ALPS driver where we had limit the quirk for trackstick handling from being active on all Dells to just a few models - a fix for a build dependency issue in the sur40 driver - a small clock handling fixup in the LPC32xx touchscreen driver * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: alps - only the Dell Latitude D420/430/620/630 have separate stick button bits Input: sur40 - add dependency on VIDEO_V4L2 Input: lpc32xx_ts - fix warnings caused by enabling unprepared clock

If common clock framework is configured, the driver generates a warning, which is fixed by this change: root@devkit3250:~# cat /dev/input/touchscreen0 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 720 at drivers/clk/clk.c:727 clk_core_enable+0x2c/0xa4() Modules linked in: sc16is7xx snd_soc_uda1380 CPU: 0 PID: 720 Comm: cat Not tainted 4.3.0-rc2+ #199 Hardware name: LPC32XX SoC (Flattened Device Tree) Backtrace: [<>] (dump_backtrace) from [<>] (show_stack+0x18/0x1c) [<>] (show_stack) from [<>] (dump_stack+0x20/0x28) [<>] (dump_stack) from [<>] (warn_slowpath_common+0x90/0xb8) [<>] (warn_slowpath_common) from [<>] (warn_slowpath_null+0x24/0x2c) [<>] (warn_slowpath_null) from [<>] (clk_core_enable+0x2c/0xa4) [<>] (clk_core_enable) from [<>] (clk_enable+0x24/0x38) [<>] (clk_enable) from [<>] (lpc32xx_setup_tsc+0x18/0xa0) [<>] (lpc32xx_setup_tsc) from [<>] (lpc32xx_ts_open+0x14/0x1c) [<>] (lpc32xx_ts_open) from [<>] (input_open_device+0x74/0xb0) [<>] (input_open_device) from [<>] (evdev_open+0x110/0x16c) [<>] (evdev_open) from [<>] (chrdev_open+0x1b4/0x1dc) [<>] (chrdev_open) from [<>] (do_dentry_open+0x1dc/0x2f4) [<>] (do_dentry_open) from [<>] (vfs_open+0x6c/0x70) [<>] (vfs_open) from [<>] (path_openat+0xb4c/0xddc) [<>] (path_openat) from [<>] (do_filp_open+0x40/0x8c) [<>] (do_filp_open) from [<>] (do_sys_open+0x124/0x1c4) [<>] (do_sys_open) from [<>] (SyS_open+0x2c/0x30) [<>] (SyS_open) from [<>] (ret_fast_syscall+0x0/0x38) Signed-off-by: Vladimir Zapolskiy Signed-off-by: Dmitry Torokhov

Pull input fixes from Dmitry Torokhov: "Just two small fixups to ads7846 touchscreen controller driver and Cypress touchpad driver" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: cyapa - fix the copy paste error on electrodes_rx value Input: ads7846 - correct the value got from SPI

Input: ads7846 - correct the value got from SPI

2015-10-06T23:39:14Z

According to the touch controller spec, SPI return a 16 bit value, only 12 bits are valid, they are bit[14-3]. The value of MISO and MOSI can be configured when SPI is in idle mode. Currently this touch driver assumes the SPI bus sets the MOSI and MISO in low level when SPI bus is in idle mode. So the bit[15] of the value got from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO in high level during the SPI idle mode, the bit[15] of the value get from SPI is always 1. If bit[15] is not masked, we may get the wrong value. Mask the invalid bit to make sure the correct value gets returned. Regardless of the SPI bus idle configuration.

imx6ul_adc_init() may fail in two cases, so we should better propagate the errors and make sure that the callers of this function also check and propagate the errors accordingly. Signed-off-by: Fabio Estevam Signed-off-by: Dmitry Torokhov
