treewide: refresh kmalloc_obj() conversionsThis is another run of the Coccinelle script for converting kmalloc()family of allocations to kmalloc_obj() via the existing rules inscripts/coccinelle/api/kmalloc_objs.cocciThis catches both the set of kmalloc() uses added since the firstkmalloc_obj() conversions in v7.0 and adds a large group missed in thefirst pass due to Coccinelle not interacting well with the cleanup.hscoped_...() family of macros[1]. I worked around this with spatch's"--macro-file" argument to a file with all the scoped_...() macros mappedto Coccinelle's YACFE_ITERATOR[2] as that was the closest viable controlflow indicator I could find.Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,riscv, and s390 with no new warnings.Link: https://lore.kernel.org/lkml/202609021314.8A9C0B8@keescook/ [1]Link: https://github.com/coccinelle/coccinelle/blob/master/standard.h [2]Signed-off-by: Kees Cook List of files: /linux/drivers/i3c/master/amd-i3c-master.c

629a6ddd1d9a0f7cc609f11822fbd5fac819a475 - i3c: master: Add driver for AMD AXI I3C master controller

Thu, 09 Jul 2026 08:42:33 +0200

i3c: master: Add driver for AMD AXI I3C master controllerAdd an I3C master driver and maintainers fragment for the AMD I3C buscontroller.The driver currently supports the I3C bus operating in SDR mode,with features including Dynamic Address Assignment, private datatransfers, and CCC transfers in both broadcast and direct modes. Italso supports operation in I2C mode.The controller's data FIFOs are accessed big-endian; the driver performsthis conversion locally using ioread32be()/iowrite32be() with thehelpers, so it does not depend on any core FIFO-endianness helpers.Signed-off-by: Manikanta Guntupalli Co-developed-by: Shubhrajyoti Datta Signed-off-by: Shubhrajyoti Datta Co-developed-by: Shubham Patil Signed-off-by: Shubham Patil Reviewed-by: Frank Li Link: https://patch.msgid.link/20260709064233.1451482-3-shubhamsanjay.patil@amd.comSigned-off-by: Alexandre Belloni List of files: /linux/drivers/i3c/master/amd-i3c-master.c
