Hi all,
After merging the sound tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
sound/hda/hdac_bus.c: In function 'snd_hdac_aligned_read':
sound/hda/hdac_bus.c:228:6: error: implicit declaration of function 'readl'; did you mean 'd_real'? [-Werror=implicit-function-declaration]
v = readl(aligned_addr);
^~~~~
d_real
sound/hda/hdac_bus.c: In function 'snd_hdac_aligned_write':
sound/hda/hdac_bus.c:244:2: error: implicit declaration of function 'writel' [-Werror=implicit-function-declaration]
writel(v, aligned_addr);
^~~~~~
Caused by commit
19abfefd4c76 ("ALSA: hda: Direct MMIO accesses")
I have applied the following patch for today:
