treewide: refresh kmalloc_obj() conversionsgrafted
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.

+config SOUND_OSS_CORE_PRECLAIM
+ bool "Preclaim OSS device numbers"
+ depends on SOUND_OSS_CORE
+ default y
+ help
+ With this option enabled, the kernel will claim all OSS device
+ numbers if any OSS support (native or emulation) is enabled
+ whether the respective module is loaded or not and try to load the
+ appropriate module using sound-slot/service-* and char-major-*
+ module aliases when one of the device numbers is opened. With
+ this option disabled, kernel will only claim actually in-use
+ device numbers and opening a missing device will generate only the
+ standard char-major-* aliases.
+
+ The only visible difference is use of additional module aliases
+ and whether OSS sound devices appear multiple times in
+ /proc/devices. sound-slot/service-* module aliases are scheduled
+ to be removed (ie. PRECLAIM won't be available) and this option is
+ to make the transition easier. This option can be overridden
+ during boot using the kernel parameter soundcore.preclaim_oss.
+
+ Disabling this allows alternative OSS implementations.
+
+ If unsure, say Y.
