Reported by smatch: drivers/media/pci/ddbridge/ddbridge-core.c:1246 input_tasklet() warn: this loop depends on readl() succeeding drivers/media/pci/ddbridge/ddbridge-core.c:1768 flashio() warn: this loop depends on readl() succeeding drivers/media/pci/ddbridge/ddbridge-core.c:1788 flashio() warn: this loop depends on readl() succeeding Fix this by introducing safe_ddbreadl() which will wrap ddbreadl and checks for all bits set in the return which indicates failure, and return 0 in that case. Usable as drop-in-replacement in all affected while loops w/o having to change the logic.
