With packet sizes other than 512, payloads in the packets may wrap

this is v3 of the f_uac2 timing fixup series.
Changes from v2:
* swap path 3 and 4, so that the ALSA buffer wrap around fix
comes in first. It's not actually a bug fix for the current
code, but more a preparation to allow for smaller packets.
* use the
The UAC2 function driver currently responds to all packets at all times
with wMaxPacketSize packets. That results in way too fast audio
playback as the function driver (which is in fact supposed to define
the audio stream pace) delivers as fast as it can.
Fix this by pre-calculating the size of
In afunc_bind() and afunc_set_alt(), uac2-pdev.dev are used multiple
times. Adding a short-hand for them makes lines shorter so we can
remove some line wraps.

Hi,
this is v4 of the f_uac2 timing fixup series.
Changes from v3:
* add another patch (3/5) to introduce agdev_to_uac2_opts()
which is also needed in 5/5
* patch 5/5 only:
move from a pre-calculated sequence of packet lengths to
an accumulator that
Restructure some code to make it easier to read.
While at it, return -ENOMEM instead of -EINVAL if
usb_ep_alloc_request() fails, and omit the logging in such cases
(the mm core will complain loud enough).

In afunc_bind() and afunc_set_alt(), uac2-pdev.dev are used multiple
times. Adding a short-hand for them makes lines shorter so we can
remove some line wraps.
No functional change.

Add a simple container_of() wrapper to get a struct f_uac2_opts from a
struct struct audio_dev. Use it in two places where it is currently
open-coded.

The UAC2 function driver currently responds to all packets at all times
with wMaxPacketSize packets. That results in way too fast audio
playback as the function driver (which is in fact supposed to define
the audio stream pace) delivers as fast as it can.
Fix this by sizing each packet correctly
With packet sizes other than 512, payloads in the packets may wrap
around the ALSA dma buffer partially, which leads to memory corruption
and audible clicks and pops in the audio stream at the moment, because
there is no boundary check before the memcpy().

Hi,
Sebastian, could you give these patches a try? They seem to work well
on a BBB setup here.
Patch v3 works great on BBB as well with a Audio Loop and 48kHz/16 bit.
No noise or clicks. Tomorrow I have time to test other combinations
