Subject: [media] m88ds3103: do not return error from get_frontend() when not ready
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9240c384f1c7cbf7ba15ccf818f37fad69fd4712;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] m88ds3103: do not return error from get_frontend() when not ready

Do not return error from get_frontend() when status is queried, but
the frontend didn't lock yet. The proper behavior is to only update the
cache after having a lock.
