2019-07-24Input: mxs-lradc-ts - use devm_platform_ioremap_resource()Mukesh Ojha1-7/+3
devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly.

2017-10-27Input: mxs-lradc - remove redundant assignment to pointer inputColin Ian King1-1/+1
The pointer 'input' is being initialized with ts->ts_input and this value is not being read as it is updated a few lines later with the return value from the call to devm_input_allocate_device. Remove the redundant initialization assignment.

2017-08-14Input: mxs-lradc - use correct error checkPan Bian1-2/+2
Function devm_ioremap() will return a NULL pointer on failure. However, in function mxs_lradc_ts_probe(), its return value is checked with IS_ERR(), which cannot detect the exceptional case. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
