From 5f976f58917eafbd8f725b9b7c0efcf6937e0e83 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 12 May 2017 10:02:08 +0200 Subject: ALSA: vx222: Use container_of() The vx222 driver is using the explicit cast from the parent class pointer, but it'll be broken when the structure field randomization is applied. Use container_of() in a modern manner, instead.

The first major change is that the kconfig items for the sequencer are moved to sound/core/seq/Kconfig. OK, that's easy. The substantial change is that, instead of hackish top-level module selection in Makefile, we define a Kconfig item for each sequencer module. The driver that requires such sequencer components select exclusively the kconfig items. This is more straightforward and standard way.

In the current code, this mechanism doesn't work when the driver is built-in while the sequencer is module. We check with IS_REACHABLE() and enable only when the sequencer is in the same level of build. However, this is basically a overshoot. The binder code (snd-seq-device) is an individual module from the sequencer core (snd-seq), and we just have to make the former a built-in while keeping the latter a module for allowing the scenario like the above. This patch achieves that by rewriting Kconfig slightly. Now, a driver that provides the manual sequencer device binding should select CONFIG_SND_SEQ_DEVICE in a way as select SND_SEQ_DEVICE if SND_SEQUENCER != n Note that the "!=n" is needed here to avoid the influence of the sequencer core is module while the driver is built-in. Also, since rawmidi.o may be linked with snd_seq_device.o when built-in, we have to shuffle the code to make the linker happy. (the kernel linker isn't smart enough yet to handle such a case.) That is, snd_seq_device.c is moved to sound/core from sound/core/seq, as well as Makefile. Last but not least, the patch replaces the code using IS_REACHABLE() with IS_ENABLED(), since now the condition meets always when enabled.

This fixed the potential problems on IVB, but now it brought another issue on HSW and BDW. These two platforms give two individual HD-audio controllers, one for the analog codec on PCH and another for HDMI over gfx. Since I decided to take a lazy path to check only AZX_DRIVER_PCH type in the commit above, now both controllers try to bind with i915, and you see a kernel WARNING. This patch tries to address it again properly. Now a new DCAPS bit, AZX_DCAPS_I915_COMPONENT, is introduced for indicating the binding with i915 component in addition to the existing I915_POWERWELL bit flag. Each PCI entry has to give this new flag if it requires the binding with i915 component. For HSW/BDW PCH (i.e. the ones defined by AZX_DCAPS_INTEL_PCH) doesn't contain AZX_DCAPS_I915_COMPONENT bit while others have it. While we're at it, add parentheses around the bit flag check for avoiding possible compiler warnings, too. The bug was spotted by Intel CI tests.
