ALSA: usb-audio/line6: Add support for POD HD PRO

2026-04-21T08:07:45+00:00

The POD HD PRO is the rackmount version of the POD 500, with most of the
same behaviors. As with some of the other rackmount POD devices it will
not send captured audio to the host unless the host is sending playback
audio, so it has LINE6_CAP_IN_NEEDS_OUT in addition to the POD 500
flags.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

ALSA: line6: add support for POD HD Pro X

2025-11-02T08:53:04+00:00

It uses the same protocol as other POD HD models so it just needed
proper config.

ALSA: line6: Use guard() for spin locks

2025-09-10T11:20:01+00:00

Clean up the code using guard() for spin locks.

Merely code refactoring, and no behavior change.

ALSA: line6: Use guard() for mutex locks

2025-09-01T11:54:06+00:00

Replace the manual mutex lock/unlock pairs with guard() for code
simplification.  The core code of line6_pcm_release() is factored out,
so that it can be covered by guard() nicely, too.

Only code refactoring, and no behavior change.

ALSA: line6: Use safer strscpy() instead of strcpy()

2025-07-11T07:53:35+00:00

Use a safer function strscpy() instead of strcpy() for copying to
arrays.

Only idiomatic code replacement, and no functional changes.

ALSA: line6: convert timeouts to secs_to_jiffies()

2025-01-13T04:21:05+00:00

Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies().  As the value here is a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication.

This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with
the following Coccinelle rules:

@@ constant C; @@

- msecs_to_jiffies(C * 1000)
+ secs_to_jiffies(C)

@@ constant C; @@

- msecs_to_jiffies(C * MSEC_PER_SEC)
+ secs_to_jiffies(C)
