Hi,
this is a v2 patch series for adapting more devres usages in ALSA drivers, a resurrect of my early RFC patch with the fix and applying to more drivers. The main purpose is merely the code cleanup over the tree by replacing the resource allocations with devres helpers as much as possible.
The only major change is the addition of devres-supported card object handling snd_devm_card_new() and the page allocation helper snd_devm_alloc_pages(). Those allow us to get rid of the remove callback completely in many drivers. In the end, the series resulted in a significant amount of code reduction.
Now ISA drivers and a few other drivers have been covered as well as a couple of missing PCI drivers and fixes.

v1->v2: * Rearrange patch order * Use size_t in snd_devm_card_new() * Move card->releasing check into devres release * Most of ISA drivers are included * A few platform drivers included * Fixed missing initializations, etc in a few drivers.
