-Subject: [PATCH] media: bcm2835-unicam: Always service interrupts
-
-From when bringing up the driver, there was a check in the isr
-to ignore interrupts (claiming them handled) should the driver
-not be streaming.
-
-The VPU now will not register a camera driver if it finds a
-CSI2 node enabled in device tree, therefore this flawed check is
-redundant.
