The single pinmux controller can be cascaded to the other interrupt controllers. Hence when propagating wake-up settings to its parent interrupt controller, there's possiblity of detecting possible recursive locking and getting lockdep warning. This patch avoids this false positive by using a separate lockdep class for this single pinctrl interrupts. Cc: Linus Walleij <redacted> Cc: linux-gpio@vger.kernel.org Suggested-by: Thomas Gleixner <redacted> Signed-off-by: Sudeep Holla <redacted>I need Tony's ACK on this patch before applying. Is it a regression that needs to go into fixes?
Not really, only needed by PATCH 2/2 to avoid recursive locking. -- Regards, Sudeep
