addresses two bug fixes and two cleanups in the pca954x\nI2C mux driver.\n\nPatches 1-2 fix resource lifecycle issues in pca954x_cleanup():\n\n - Patch 1 reorders cleanup so that child adapters are removed before\n the regulator is disabled, ensuring children are torn down while\n the device is still powered.\n\n - Patch 2 quiesces the parent IRQ via devm_free_irq() before removing\n child adapters and tearing down the IRQ domain. The threaded handler\n dispatches nested child IRQs over the mux, so it must be stopped\n before either child adapters or the IRQ domain are dismantled.\n Because pca954x_cleanup() is also used as the probe error-unwind\n path and the IRQ domain is created before the parent IRQ is\n requested, a flag guards the devm_free_irq() call so it is only\n issued when the managed IRQ was actually registered.\n\nPatches 3-4 are straightforward cleanups:\n\n - Patch 3 replaces sprintf() with sysfs_emit() in idle_state_show().\n - Patch 4 marks pca954x_irq_chip as const with IRQCHIP_IMMUTABLE.\n\nSanman Pradhan (4):\n i2c: muxes: pca954x: fix cleanup ordering in pca954x_cleanup()\n i2c: muxes: pca954x: free parent IRQ before dismantling IRQ domain\n i2c: muxes: pca954x: use sysfs_emit() in idle_state_show()\n i2c: muxes: pca954x: mark irq_chip as immutable\n\n drivers/i2c/muxes/i2c-mux-pca954x.c | 18 ++++++++++++++----\n 1 file changed, 14 insertions(+), 4 deletions(-)" }
