sunxi-5.16: Fix spi-nor node initialization error for orangepi-pc2#3597
Merged
Conversation
The problem was solved in the upstream kernel. commit e221ef82d9f5e97bca61f7c25e2b58b04466de87 linux-5.16.y branch. commit bac129dbc6560dfeb634c03f0c08b78024e71915 upstream. This driver, like several others, uses a chained IRQ for each GPIO bank, and forwards .irq_set_wake to the GPIO bank's upstream IRQ. As a result, a call to irq_set_irq_wake() needs to lock both the upstream and downstream irq_desc's. Lockdep considers this to be a possible deadlock when the irq_desc's share lockdep classes, which they do by default: ============================================ WARNING: possible recursive locking detected 5.17.0-rc3-00394-gc849047c2473 #1 Not tainted ...
