      media: ddbridge: don't uselessly check for dma in start/stop functions · 8b8fcf32
      Daniel Scheller authored
      The check for a valid ptr in ddb_io->dma isn't really necessary since only
      devices that do data transport using DMA are supported by the driver, and
      all previous initialisation code (through input_init(), output_init() and
      dma_init(), has_dma is always true as it's set in ddb_probe() during
      driver load) guarantees the ptr is set.
      
      As a side effect, this silences these sparse warnings (albeit them being
      false positives as ddb_io->dma won't change in these functions so the
      condition always equals to the same result):

      media: mantis: prevent staying forever in a loop at IRQ · cac61a1a
      Mauro Carvalho Chehab authored
      As warned by smatch:
      	drivers/media/pci/mantis/mantis_uart.c:105 mantis_uart_work() warn: this loop depends on readl() succeeding
      
      If something goes wrong at readl(), the logic will stay there
      inside an IRQ code forever. This is not the nicest thing to
      do :-)
      
      So, add a timeout there, preventing staying inside the IRQ
      for more than 10ms.

      media: atomisp: get rid of a warning · ca33f8f6
      Mauro Carvalho Chehab authored
      On smatch, this warning is trigged:
      
      	drivers/staging/media/atomisp/pci/atomisp2/hmm/hmm_bo.c:324 __bo_take_off_handling() error: we previously assumed 'bo->prev' could be null (see line 314)
      
      Because it can't properly analize the truth table for the above
      function. So, add an explicit check for the final condition there.
