From: Hans de Goede <hdego...@redhat.com> [ Upstream commit bb18c678754ce1514100fb4c0bf6113b5af36c48 ]
Most steps in this table are steps of 3dB (300 centi-dB), so we can simplify the table. This not only reduces the amount of space it takes inside the kernel, this also makes alsa-lib's mixer code actually accept the table, where as before this change alsa-lib saw the "ADC PGA Gain" control as a control without a dB scale.
