Subject: atp870u: Add channel parameter to is870() and is880()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bdf8b62dc3fb2ef5df22d36d1d2ec1d38e081290;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

atp870u: Add channel parameter to is870() and is880()

Add channel parameter to is870() and is880() functions to simplify comparing
them with is885().
