Input: raydium_i2c_ts - use managed devm_device_add_group

2017-09-29T23:51:04+00:00

Commit 57b8ff070f98 ("driver core: add devm_device_add_group() and
friends") has added the managed version for creating sysfs group files.

Use devm_device_add_group instead of sysfs_create_group and remove the
action that cleans the sysfs file when exiting the driver.

Input: raydium_i2c_ts - constify attribute_group structures

2017-07-12T21:19:29+00:00

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by  work with const
attribute_group. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   7801	    560	      0	   8361	   20a9	drivers/input/touchscreen/raydium_i2c_ts.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   7849	    496	      0	   8345	   2099	drivers/input/touchscreen/raydium_i2c_ts.o

Input: touchscreen - drop unnecessary calls to input_set_drvdata

2017-01-23T01:22:31+00:00

Since there is no call to dev_get_drvdata() or input_get_drvdata(),
the call to input_set_drvdata() is unnecessary and can be dropped.

Input: raydium_i2c_ts - do not ignore EPROBE_DEFER from gpiod_get_optional

2016-06-01T18:18:59+00:00

We should not be ignoring -EPROBE_DEFER reported by
devm_gpiod_get_optional(), but report it as any other error to the upper
layers. While we are at it simplify check for the presence of reset GPIO
and instead of using IS_ERR_OR_NULL just use boolean.

Also do not return -ENOMEM from suspend handler when the device in
bootloader mode as that does not make sense and switch to -EBUSY instead.
