Subject: [PATCH V3] i2c-algo-pca: fix coding style issues in i2c-algo-pca.c

This patch fixes up some coding style issues. i2c-algo-pca.c has been
build successfully after applying this patch and the binary object is
still exactly the same.
Other issues found by checkpatch.pl were voluntarily not fixed, either
to keep readability, or because of false positive errors.
