media: cx23885: Handle additional bufs on interrupt On Ryzen systems interrupts are occasionally missed: cx23885: cx23885_wakeup: [ffff99b384b83c00/28] wakeup reg=5406 buf=5405 cx23885: cx23885_wakeup: [ffff99b40bf79400/31] wakeup reg=9537 buf=9536 This patch loops up to five times on wakeup, marking any buffers found done. Since the count register is u16, but the vb2 counter is u32, some modulo arithmetic is used to accommodate wraparound and ensure current active buffer is the buffer expected.
