2017-01-18Input: mma8450 - drop unnecessary call to i2c_set_clientdataGuenter Roeck1-2/+0
There is no call to i2c_get_clientdata() or dev_get_drvdata(). Drop the unnecessary call to i2c_set_clientdata(). Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-03-24Input: mma8450 - convert to using managed resourcesDmitry Torokhov1-27/+8
This simplifies error handling and device removal code. Also let's get rid of setting driver's owner since i2c core does it for us. Tested-by: Stefan Sauer <ensonic@google.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-02-26Input: mma8450 - add parent deviceStefan Sauer1-0/+1
Add the parent device so that udev can show the full hierarchy. This avoids the device showing up under /devices/virtual/input instead of the i2c bus it is actually attached to. Signed-off-by: Stefan Sauer <ensonic@google.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-11-11Input: mma8450 - add missing i2c_set_clientdata() in mma8450_probe()Wei Yongjun1-1/+3
Add missing i2c_set_clientdata() in mma8450_probe(), otherwise calling i2c_get_clientdata() in mma8450_remove() returns NULL. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2013-03-31Input: mma8450 - fix signed 12bits to 32bits conversionSebastien Royen1-3/+3
Event value is wrong. Should be in range -2048 to 2047, but is in range 0 to 4095. Use s8 to int conversion and remove 0xfff mask. Signed-off-by: Sebastien Royen <sebastien.royen@armadeus.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2012-11-24Input: remove use of __devexitBill Pemberton1-1/+1
CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2012-03-17Input: convert I2C drivers to use module_i2c_driver()Axel Lin1-11/+1
This patch converts the drivers in drivers/input/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-10-07Input: mma8450 - silence some 'uninitialized variable' warningsDmitry Torokhov1-10/+10
Sometimes GCC is not smart enough to recognize that x, y and z are always used properly initialized in mma8450_poll(). Let's rearrange the code a bit to help GCC. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-08-09Input: mma8450 - fix module device table typeAxel Lin1-1/+1
The module device table for of_device_id should use "of" type. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
