Subject: [media] marvell-ccic: drop free_irq for devm_request_irq allocated irq
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=23c4919c6fd15e76fe245ad0158f8739a3fa0747;p=linux-beck.git

[media] marvell-ccic: drop free_irq for devm_request_irq allocated irq

irq allocated with devm_request_irq should not be freed using
free_irq, because doing so causes a dangling pointer, and a
subsequent double free.
