[ALSA] #3/4 for Zoom Video - change Hardware Volume interrupt handling
Modules: ES18xx driver Third of 4 es18xx.c patches culminating in Zoom Video support. This patch changes the Hardware Volume support to reflect the fact that not all of the supported chipsets have seperate registers dedicated to the Hardware Volume inputs. Although all the chipsets can generate an HWV interrupt whenever a Hardware Volume input is received only those with seperate HWV registers can split the HWV registers from the Master volume registers. Testing: This work was initially done on the source from the Debian Sarge ALSA package, then tested on an ES1879 and an ES1878 machine. Patches were created against the Sarge code and then edited to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs code was test for successful compilation. No additional testing was done on the ALSA cvs version. Signed-off-by: Mark Salazar <markTheCoder@justmyself.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
