[PATCH OLK-5.10] drm/omap: fix misleading indentation in pixinc()

From: Arnd Bergmann <arnd(a)arndb.de> mainline inclusion from mainline-v5.13-rc1 commit 417fc6123b4a60c60b770e756cc3e001d764e480 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID96N8 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- An old patch added a 'return' statement after each BUG() in this driver, which was necessary at the time, but has become redundant after the BUG() definition was updated to handle this properly. gcc-11 now warns about one such instance, where the 'return' statement was incorrectly indented: drivers/gpu/drm/omapdrm/dss/dispc.c: In function ‘pixinc’: drivers/gpu/drm/omapdrm/dss/dispc.c:2093:9: error: this ‘else’ clause does not guard... [-Werror=misleading-indentation] 2093 | else | ^~~~ drivers/gpu/drm/omapdrm/dss/dispc.c:2095:17: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘else’ 2095 | return 0; | ^~~~~~ Address this by removing the return again and changing the BUG() to be unconditional to make this more intuitive.

[PATCH OLK-6.6] bpf: Sync pending IRQ work before freeing ring buffer

From: Noorain Eqbal <nooraineqbal(a)gmail.com> stable inclusion from stable-v6.6.117 commit 6451141103547f4efd774e912418a3b4318046c6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID95VB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4e9077638301816a7d73fa1e1b4c1db4a7e3b59c ] Fix a race where irq_work can be queued in bpf_ringbuf_commit() but the ring buffer is freed before the work executes. In the syzbot reproducer, a BPF program attached to sched_switch triggers bpf_ringbuf_commit(), queuing an irq_work. If the ring buffer is freed before this work executes, the irq_work thread may accesses freed memory. Calling `irq_work_sync(&rb->work)` ensures that all pending irq_work complete before freeing the buffer.
