Subject: ALSA: hda - fix Lewisburg audio issue
From: Jaroslav Kysela <[email protected]>
commit e7480b34ad1ab84a63540b2c884cb92c0764ab74 upstream.
Like for Sunrise Point, the total stream number of Lewisburg's input and output stream exceeds 15 (GCAP is 0x9701), which will cause some streams do not work because of the overflow on SDxCTL.STRM field if using the legacy stream tag allocation method.
