In my opinion the above patch simply reworks the explanation, shifting the "magic" from the PIN_* definitions to the AC_PINCTL_* defines. One could take things one step further and replace the PIN_* defines with AC_PINCTL_* references throughout the code, but this would make the code far more verbose and harder to follow. At the end of the day I'm not fussed either way. Having said that, I don't really see the practical advantage of the change but if Takashi et al thing it's a good idea then I wouldn't oppose it.

[alsa-devel] [PATCH 0/7] HDA patch_via.c update
by Harald Welte 16 Sep '08

16 Sep '08

Hi! As part of my work for VIA I have stumbled upon their current internal HDA codec driver and it's various differences against the current mainline driver. I have spent the better part of two days separating the individual changesets out of the big diff between VIA's driver and current mainline linux-2.6 (which is identical to alsa-kernel.git). After this merge, I will work with product management and R&D inside VIA that all individual changesets (bugfixes / enhancements) will be sent ASAP for mainline inclusion to prevent any large differencees betwee the two trees. If you have any questions regarding VIA's hardware or need access to data sheets or the like, I am happy to assist. -- - Harald Welte <HaraldWelte(a)viatech.com> http://linux.via.com.tw/ ============================================================================ VIA Open Source Liaison

Hi! Unfortunately there is one crash (headphone related), one non-working feature (second S/PDIF out) and one regular bugfix since my seven-patch series from last week. Please review + apply the following patches to your tree. I've tested them against sound-2.6/topic/hda and they apply fine. If you have any questions, please keep Logan Li in the Cc, he is the engineer who actually implemented those changes and knows all the details.
