media: i2c: Fix pm_runtime_get_if_in_use() usage in sensor drivers
pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This
should not be considered an error. Generally the driver has enabled
runtime PM already so getting this error due to runtime PM being disabled
will not happen.
Instead of checking for lesser or equal to zero, check for zero only.
Address this for drivers where this pattern exists.
This patch has been produced using the following command:
$ git grep -l pm_runtime_get_if_in_use -- drivers/media/i2c/ | \
xargs perl -i -pe 's/(pm_runtime_get_if_in_use\(.*\)) \<\= 0/!$1/'
