From: Geoffrey D. Bennett Date: Thu, 26 Oct 2023 18:06:16 +0000 (+1030) Subject: ALSA: scarlett2: Allow passing any output to line_out_remap() X-Git-Tag: v6.6.14~262 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=66fb87fac545583bfb441bc4d6dffd99a7b38a48;p=platform%2Fkernel%2Flinux-starfive.git ALSA: scarlett2: Allow passing any output to line_out_remap() [ Upstream commit 2190b9aea4eb92ccf3176e35c17c959e40f1a81b ] Line outputs 3 & 4 on the Gen 3 18i8 are internally the analogue 7 and 8 outputs, and this renumbering is hidden from the user by line_out_remap(). By allowing higher values (representing non-analogue outputs) to be passed to line_out_remap(), repeated code from scarlett2_mux_src_enum_ctl_get() and scarlett2_mux_src_enum_ctl_put() can be removed.
