[PATCH 01/15] serial: sc16is7xx: remove useless enable of enhanced features

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Commit 43c51bb573aa ("sc16is7xx: make sure device is in suspend once probed") permanently enabled access to the enhanced features in sc16is7xx_probe(), and it is never disabled after that. Therefore, remove useless re-enable of enhanced features in sc16is7xx_set_baud().

[PATCH] asm-generic/io.h: Skip trace helpers if rwmmio events are disabled

by Varad Gautam

With `CONFIG_TRACE_MMIO_ACCESS=y`, the `{read,write}{b,w,l,q}{_relaxed}()` mmio accessors unconditionally call `log_{post_}{read,write}_mmio()` helpers, which in turn call the ftrace ops for `rwmmio` trace events This adds a performance penalty per mmio accessor call, even when `rwmmio` events are disabled at runtime (~80% overhead on local measurement). Guard these with `tracepoint_enabled()`.

[PATCH 6.12.y 1/3] drm/sched: Optimise drm_sched_entity_push_job

by Jules Maselbas

From: Tvrtko Ursulin <tvrtko.ursulin(a)igalia.com> commit d42a254633c773921884a19e8a1a0f53a31150c3 upstream. In FIFO mode (which is the default), both drm_sched_entity_push_job() and drm_sched_rq_update_fifo(), where the latter calls the former, are currently taking and releasing the same entity->rq_lock. We can avoid that design inelegance, and also have a miniscule efficiency improvement on the submit from idle path, by introducing a new drm_sched_rq_update_fifo_locked() helper and pulling up the lock taking to its callers. v2: * Remove drm_sched_rq_update_fifo() altogether. (Christian) v3: * Improved commit message.

[PATCH v2] comedi: fix divide-by-zero in comedi_buf_munge()

by Deepanshu Kartikey

The comedi_buf_munge() function performs a modulo operation `async->munge_chan %= async->cmd.chanlist_len` without first checking if chanlist_len is zero. If a user program submits a command with chanlist_len set to zero, this causes a divide-by-zero error when the device processes data in the interrupt handler path. Add a check for zero chanlist_len at the beginning of the function, similar to the existing checks for !map and CMDF_RAWDATA flag. When chanlist_len is zero, update munge_count and return early, indicating the data was handled without munging. This prevents potential kernel panics from malformed user commands.
