Subject: [PATCH 2/2] Use __compat_aligned_s64 in uapi <sound/asound.h>
Date: Wed, 25 Dec 2013 09:17:46 -0800 [thread overview]
Message-ID: <20131225171746.GA1826@gmail.com> (raw)
The integer64 field in struct snd_ctl_elem_value has different offsets,
depending the alignment of long long. This patch replaces long long
with the newly introduced __compat_aligned_s64 so that x32 and ia32
can use the same compat system call for struct snd_ctl_elem_value.
