treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

ALSA: sparc/dbri: Fix "possible condition with no effect" warning

2026-07-19T08:42:22+00:00

Fix a compiler warning about a condition with no effect: sound/sparc/dbri.c:1843:1-3: WARNING: possible condition with no effect (if == else) When DBRI_DEBUG is not defined, dprintk expands to an empty do-while statement, making both branches of the if-else no-ops. Guard the entire debug block with #ifdef DBRI_DEBUG to eliminate the warning and keep the rval reference consistent with its declaration scope.

ALSA: sparc: 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. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250710100727.22653-93-tiwai@suse.de

ALSA: amd7930: replace strcpy() with strscpy()

2025-05-20T14:07:18+00:00

strcpy() is deprecated; use strscpy() instead. Both the destination and source buffer are of fixed length so strscpy with 2-arguments is used. No functional changes intended.
