media: rkisp1: Fix IRQ handler return values
[ Upstream commit 3eb7910e1b16a2c136be26a8380f21469225b2f6 ]
The IRQ handler rkisp1_isr() calls sub-handlers, all of which returns an
irqreturn_t value, but rkisp1_isr() ignores those values and always
returns IRQ_HANDLED.
Fix this by collecting the return values, and returning IRQ_HANDLED or
IRQ_NONE as appropriate.
