[PATCH 5.10 066/317] macintosh/via-macii: Fix "BUG: sleeping function called from invalid context"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Finn Thain <fthain@xxxxxxxxxxxxxx>

[ Upstream commit d301a71c76ee4c384b4e03cdc320a55f5cf1df05 ]

The via-macii ADB driver calls request_irq() after disabling hard
interrupts. But disabling interrupts isn't necessary here because the
VIA shift register interrupt was masked during VIA1 initialization.
