media: mantis: prevent staying forever in a loop at IRQ 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. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
