Subject: Input: atmel_mxt_ts - only allow root to update firmware
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=71b3e938cb97f6cf324fb5aaca46d8e400dc38f0;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Input: atmel_mxt_ts - only allow root to update firmware

Restrict permissions on the update_fw sysfs entry to read only for root
only.

Also, update object permission to use a macro S_IRUGO macro instead of
hard coded 0444.
