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.
