Marc Zyngier a2cb9aeb3c gpio: fix pca953x set_type 'scheduling while atomic' bug ... Bill Gatliff reported the following bug when using the irq_chip facility of the pca953x driver on a PPC platform: BUG: scheduling while atomic: insmod/1530/0x00000002 He traced it back to an i2c transaction in pca953x_irq_set_type(), which can be called with interrupt disabled (from __setup_irq()). As the i2c controller can sleep while sending a message, this qualifies as a bad idea. This patch moves the i2c transaction to pca953x_irq_bus_sync_unlock(), where it is actually safe to send an i2c message.
