2026-01-20kernel.h: drop hex.h and update all hex.h usersRandy Dunlap
Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of hex.h interfaces to directly #include <linux/hex.h> as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of <linux/hex.h> in the entire source tree have been updated if needed (if not already #included).

2026-01-19ALSA: ctxfi: Fix potential OOB access in audio mixer handlingTakashi Iwai
In the audio mixer handling code of ctxfi driver, the conf field is used as a kind of loop index, and it's referred in the index callbacks (amixer_index() and sum_index()). As spotted recently by fuzzers, the current code causes OOB access at those functions. | UBSAN: array-index-out-of-bounds in /build/reproducible-path/linux-6.17.8/sound/pci/ctxfi/ctamixer.c:347:48 | index 8 is out of range for type 'unsigned char [8]' After the analysis, the cause was found to be the lack of the proper (re-)initialization of conj field. This patch addresses those OOB accesses by adding the proper initializations of the loop indices.

Add support for the Onkyo SE-300PCIE, a Creative X-Fi CA20K2-based sound card with a custom hardware implementation that differs significantly from other CA20K2-based variants. Changes: - PCI quirk entry for OK0010 - Port 0x3 is utilized for dedicated RCA output (configured as I2S) - Modified GPIO pin mappings and states - 4-channel simultaneous ADC input support for line and microphone capture without input switching (similar to SB1270) - Simplified ADC initialization (no manual setup required) Signed-off-by: Harin Lee <me@harin.net> Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20251124180501.2760421-7-me@harin.net

2025-11-17ALSA: au88x0: Fix incorrect error handling for PCI config readsHaotian Zhang
__snd_vortex_probe() uses pci_read_config_word() that returns PCIBIOS_* codes (positive values on error). However, the function checks 'err < 0' which can never be true for PCIBIOS_* codes, causing errors to be silently ignored. Check for non-zero return value and convert PCIBIOS_* codes using pcibios_err_to_errno() into normal errno before returning them.

In file included from ../sound/pci/au88x0/au8830.c:15: In function ‘vortex_Eqlzr_SetAllBandsFromActiveCoeffSet’, ../sound/pci/au88x0/au88x0_eq.c:571:9: error: ‘vortex_EqHw_SetRightGainsTarget’ reading 2 bytes from a region of size 0 [-Werror=stringop-overread] vortex_EqHw_SetRightGainsTarget(vortex, &(eq->this130[eq->this10])); Modified the array access in vortex_Eqlzr_SetAllBandsFromActiveCoeffSet() to use pointer arithmetic instead of array indexing. This resolves a compiler warning that incorrectly flagged a buffer overread when accessing the EQ gain array. The this130 array has fixed size 20 and the index is safely within bounds, making the original code correct but confusing to static analysis.
