platform/chrome: cros_ec_proto: Introduce cros_ec_read_features helper

2026-07-23T16:02:38+00:00

Extract the EC feature-reading logic from cros_ec_check_features() into cros_ec_read_features() helper function. Currently, cros_ec_check_features() swallows command transfer errors. By isolating the transaction logic into an explicit helper that returns the actual transfer error code, subsequent callers (such as the cros_ec_dev driver during device probing) can catch a read error.

mtd: nand-omap2: Move omap_nand_ids[] to raw nand driver

2026-07-17T15:48:25+00:00

Defining a static array in a header results in each .c file that includes the header (here: drivers/memory/omap-gpmc.c and drivers/mtd/nand/raw/omap2.c) to contain a copy of that array when compiled to an object file. With sizeof(struct of_device_id[3]) ≥ 588 having omap_nand_ids[] twice just to do two string comparisons is quite some bloat. So move omap_nand_ids[] to the nand driver which actually needs that array for its module meta data and do the compatible check by hand. bloat-o-meter reports for drivers/memory/omap-gpmc.o (ARCH=arm): add/remove: 1/2 grow/shrink: 1/0 up/down: 28/-588 (-560) Function old new delta gpmc_probe_generic_child 2108 2136 +28 omap_nand_ids 588 - -588 Total: Before=18114, After=17554, chg -3.09% (drivers/mtd/nand/raw/omap2.o doesn't change). This allows to drop from include/linux/platform_data/mtd-nand-omap2.h (which is my original motivation for this change). Note that this header isn't needed in the two drivers because omap-gpmc.c doesn't use any device id struct and for the nand driver omap2.c of_device_id is already provided via .

platform/x86: asus-armoury: gate PPT writes behind active fan curve

2026-07-06T08:26:57+00:00

On models flagged with requires_fan_curve in the DMI power_data table (30 entries), the BIOS ACPI method SPLX only writes PPT values to the EC when the fan mode is set to Manual (FANM=4). FANM is set to 4 by the DEFC method when a custom fan curve is written. Without an active custom fan curve, the WMI DEVS call returns success but the firmware silently ignores the PPT value, so userspace observes no effect from its write. Gate writes to ASUS_WMI_DEVID_PPT_{PL1_SPL,PL2_SPPT,PL3_FPPT,APU_SPPT, PLAT_SPPT} on a check of asus_wmi_custom_fan_curve_is_enabled(), and return -EBUSY with a pr_warn_once() when no fan curve is active on an affected model. Export the helper from asus-wmi so asus-armoury can call it across module boundaries.

is included in a many files: $ git grep '' ef0c9f75a195 | wc -l 1598 ; some of them are widely used headers. To stop mixing up different and unrelated driver( type)s let the subsystem headers only use the subset of the recently split that are relevant for them. The fallout (I hope) is addressed in the previous commits that handle sources relying on e.g. pulling in the full legacy header and thus providing pci_device_id.
