Subject: Input: intel-mid-touch - remove pointless checking for variable 'found'
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e449edbb91decd0260105fadd4f5fcc3ce170e01;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: intel-mid-touch - remove pointless checking for variable 'found'

The implementation does break from the for loop after we assign 'i' to
variable 'found'.
