Subject: hwmon: (adc128d818) Drop write support on inX_input attributes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7fe7381cbdadf16792e733789983690b3fa82880;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

hwmon: (adc128d818) Drop write support on inX_input attributes

Writes into input registers doesn't make sense, even more so since
the writes actually ended up writing into the maximum limit registers.
Drop it.
