Subject: [PATCH v2 1/4] ASoC: SDCA: make q78_get_volsw and q78_put_volsw extern
Date: Thu, 26 Mar 2026 23:47:09 +0530 [thread overview]
Message-ID: <20260326181712.2274-1-niranjan.hy@ti.com> (raw)
q78_get_volsw and q78_put_volsw are get and set functions
in sdca library to handle 16bit signed Q7.8 values for
Volume control. Make them extern so that ASoC drivers can
reuse them.
