Subject: V4L/DVB (7126): tuner: move tuner type ID check to simple_tuner_attach
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=65e8d29f7a37faaf9c73c633447bebd4b31b2c89;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

V4L/DVB (7126): tuner: move tuner type ID check to simple_tuner_attach

Move tuner type ID check from tuner-core::set_type to simple_tuner_attach.

Since tuner-core forwards all attach requests to tuner-simple as the
default case, unless a specific attach function is specified in
set_type, this change is an appropriate cleanup.
