Subject: Input: ads7846 - release resources on failure for clean exit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a1cd3fd09a9b7de710d705127aa616946b567d72;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Input: ads7846 - release resources on failure for clean exit

Input device must be released(input_free_device) when ads7846_probe_dt
fails. This fixes the same by releasing resources on failure.
