"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: realtek: use gpiod_set_value_cansleep for reset GPIO\n\nrtl83xx_reset_assert() and rtl83xx_reset_deassert() are only called from\nthe probe path, which may sleep and is not timing-critical. When the\nreset GPIO is provided by a sleeping controller such as an I2C I/O\nexpander, gpiod_set_value() warns:\n\n WARNING: drivers/gpio/gpiolib.c:4030 at gpiod_set_value+0x44/0x80, CPU#1: kworker/u16:4/61\n Hardware name: B&O MAP CA33 Rev f (UNKNOWN) (DT)\n Workqueue: events_unbound deferred_probe_work_func\n pc : gpiod_set_value+0x44/0x80\n lr : rtl83xx_probe+0x1d8/0x3a0\n Call trace:\n gpiod_set_value+0x44/0x80 (P)\n rtl83xx_probe+0x1d8/0x3a0\n realtek_mdio_probe+0x24/0xa0\n mdio_probe+0x38/0x78\n really_probe+0xc4/0x3e0\n __driver_probe_device+0x15c/0x1b8\n driver_probe_device+0xb4/0x120\n __device_attach_driver+0xb8/0x1a0\n bus_for_each_drv+0x88/0xf0\n __device_attach+0xa0/0x1d8\n device_initial_probe+0x54/0x68\n bus_probe_device+0x38/0xa0\n deferred_probe_work_func+0xb8/0x120\n process_one_work+0x184/0x4e8\n worker_thread+0x188/0x308\n kthread+0x130/0x150\n ret_from_fork+0x10/0x20\n\nSwitch both helpers to gpiod_set_value_cansleep() so such a reset GPIO can\nbe used without triggering the warning.\n\nThe reset GPIO has been driven with the non-sleeping gpiod_set_value()\nsince the driver was added in v4.19. The call has since been refactored\nacross several files - from realtek-smi.c / realtek-mdio.c into the common\nrtl83xx.c module and then into the rtl83xx_reset_assert() and\nrtl83xx_reset_deassert() helpers (both in v6.9). This patch therefore\napplies as-is only to kernels that carry those helpers (v6.9+); older\nstable kernels need the same gpiod_set_value_cansleep() conversion at the\ncorresponding open-coded call sites."
