Pull char/misc/IIO/etc driver updates from Greg KH: "Here is the big set of char, misc, iio, counter, fpga, and other small driver subsystems for 7.3-rc1. Overall, due to some driver removals we only added a bit more code than removed, which was a nice change. Highlights in this merge request are: - Loads of IIO driver updates and additions - binder driver updates (more on that below...) - Removal of the SGI XP and GRU drivers as they are not used anymore and turn out to be pretty insecure overall - Removal of the obsolete ibmasm driver as it's not being used anymore - Coresight driver updates and additions - Mei driver udpates - Counter driver updates - FPGA driver updates - ICC driver updates - lots and lots of other tiny driver updates to resolve reported issues All of these have been in linux-next for a while" * tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (513 commits) iio: chemical: atlas-sensor: use iio_trigger_poll_nested() to fix remove UAF iio: adc: pac1921: fix wrong channel used in trigger handler read iio: light: gp2ap002: re-enable irq if runtime suspend fails iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes iio: light: apds9306: fix PM reference leak in apds9306_read_data() iio: gyro: mpu3050: fix sign of raw angular velocity readings iio: srf04: fix pm_runtime handling on probe error path iio: adc: ad4080: configure backend data size iio: adc: adi-axi-adc: add data size support for AD408X backend iio: chemical: atlas-sensor: fix PM reference leak in buffer postenable iio: dac: ad5446: fix OF module device table iio: light: opt4001: Fix reversed GENMASK() arguments in fault count mask iio: light: opt4001: Reject integration times with a non-zero seconds part iio: light: opt4001: Fix incompatible pointer type passed to div_u64_rem() iio: light: opt4001: Fix power down clearing bits of the wrong register iio: light: opt4060: Fix incorrect register name in threshold read error message iio: light: opt4060: Fix pointer type passed to div_u64_rem() iio: light: opt4060: Reject integration times with a non-zero seconds part iio: light: ltrf216a: fix runtime PM reference leak in error path iio: pressure: dps310: fix NULL pointer dereference on ACPI probe ...

lib: vsprintf: use _parse_integer() instead of _parse_integer_limit()

2026-06-29T18:05:39+00:00

Use _parse_integer() that allows optional arguments to be explicitly initialised. Signed-off-by: Andy Shevchenko Acked-by: Petr Mladek Signed-off-by: Rodrigo Alencar Signed-off-by: Jonathan Cameron

lib/vsprintf: Make no_hash_pointers take effect early

2026-06-25T09:19:34+00:00

The no_hash_pointers boot parameter is now handled as an alias for hash_pointers=never. However, hash_pointers=never only records the selected mode during early parameter parsing, and no_hash_pointers is not updated until hash_pointers_finalize() runs later from SLUB init. This leaves a window during very early boot where %p output is still hashed even though the user explicitly requested unhashed pointers with no_hash_pointers or hash_pointers=never. Set no_hash_pointers as soon as the "never" mode is parsed. The later hash_pointers_finalize() call still keeps the final policy decision in one place, but explicit requests to disable pointer hashing now take effect for early boot users too.

vsprintf: Add upper case flavour to %p[mM]

2026-06-12T12:20:25+00:00

Some of the (ABI aware) code needs an upper case when printing MAC addresses. Introduce an extension for that into the existing %p[mM].

lib/vsprintf: Require exact hash_pointers mode matches

2026-05-26T09:06:12+00:00

hash_pointers= accepts a small set of mode strings, but the parser uses strncmp() with the length of each valid mode. That accepts values with trailing garbage, such as hash_pointers=autobots or hash_pointers=nevermind, as valid aliases for auto and never. Use strcmp() so that only the documented mode strings are accepted. Invalid values will continue to fall back to auto through the existing unknown-mode path.
