[alsa-devel] [PATCH] include/adriver.h: Define pr_warn to allow compilation against older kernels

[Luke Yelavich]

From: Luke Yelavich <luke.yelavich at canonical.com>

In my testing of the daily tarball, I am unable to build against 2.6.32. I
assume that older kernels would be affected in a similar way.
