Subject: [ALSA] rawmidi: adjust runtime->avail when changing output buffer size
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1b98ea4791892399d8c23c93e117567eeff38887;p=linux-beck.git

[ALSA] rawmidi: adjust runtime->avail when changing output buffer size

Modules: RawMidi Midlevel

When the output buffer size is changed, runtime->avail must be
adjusted to the new size; otherwise, draining of a bigger buffer would
appear to fail because avail does not reach buffer_size.
