A recent cleanup had the right idea to remove the initialization
of the error variable, but missed the actual benefit of that,
which is that we get warnings if there is a bug in it. Now
we get a warning about a bug that was introduced by this cleanup:
drivers/media/platform/davinci/vpfe_capture.c: In function 'vpfe_probe':
drivers/media/platform/davinci/vpfe_capture.c:1992:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This adds the missing initialization that the warning is about,
and another one that was preexisting and that we did not get
a warning for. That second bug has existed since the driver
was first added.
