Neil Armstrong 9f7406d6b5 media: platform: ao-cec-g12a: disable regmap fast_io for cec bus regmap ... With fast_io enabled, spinlock_irq is used for read/write operations, thus leading to : BUG: sleeping function called from invalid context at [snip]/ao-cec-g12a.c:379 in_atomic(): 1, irqs_disabled(): 128, pid: 1451, name: irq/14-ff800280 [snip] Call trace: dump_backtrace+0x0/0x180 show_stack+0x14/0x1c dump_stack+0xa8/0xe0 ___might_sleep+0xf4/0x104 __might_sleep+0x4c/0x80 meson_ao_cec_g12a_read+0x7c/0x164 regmap_read+0x16c/0x1b0 meson_ao_cec_g12a_irq_thread+0xcc/0x200 irq_thread_fn+0x2c/0x60 irq_thread+0x14c/0x1fc kthread+0x11c/0x12c ret_from_fork+0x10/0x18 Simply remove fast_io to use mutexes instead.
