From ce5d72b6f5a0b694b19cd812788d8e1ea49aea21 Mon Sep 17 00:00:00 2001 From: Evgeny Novikov Date: Mon, 21 Sep 2020 14:30:06 +0200 Subject: media: dvb-frontends: rtl2832_sdr: set error code in probe If rtl2832_sdr_probe() encounters an unsupported tuner it cleans up everything and returns 0. This can result in various bad things later. The patch sets the error code on the corresponding path. Found by Linux Driver Verification project (linuxtesting.org).
