ASoC: Intel: avs: Replace snprintf() with scnprintf()

2025-11-21T16:25:02+00:00

snprintf() as defined by the C99 standard,returns the number of characters that *would have been* written if enough space were available.Use scnprintf() that returns the actual number of characters written.

ASoC: Intel: avs: Separate debug symbols

2025-08-18T12:10:05+00:00

Make it clear what is part of debug functionality and what is not by separating debug symbols away from the common header file. Apart from changing avs_probe_platform_register() to return -ENOTSUPP when CONFIG_DEBUG_FS is disabled, status quo is achieved.

ASoC: Intel: Remove redundant pm_runtime_mark_last_busy() calls

2025-07-04T18:28:20+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

ASoC: Intel: avs: Verify content returned by parse_int_array()

2025-06-02T11:26:50+00:00

The first element of the returned array stores its length. If it is 0, any manipulation beyond the element at index 0 ends with null-ptr-deref.

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43+00:00

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

ASoC: Intel: avs: clarify Copyright information

2024-05-06T14:59:39+00:00

For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated. Remove the "All rights reserved" in all Intel-copyright to align with internal guidance.
