From 757d78d35aeab1e53a9025128a14d8b63b1a2ba3 Mon Sep 17 00:00:00 2001 From: Daniel Scheller Date: Sun, 15 Oct 2017 16:51:51 -0400 Subject: media: ddbridge: fixup checkpatch-strict issues Fixes several alignment, braces, space-before-cast, camelcase et al issues reported by checkpatch --strict, plus a few more checkpatch didn't report. Three checks are left after this though: - one CamelCase in ddbridge-core, related to defines/vars/enums referenced from the stv090x demod driver - one macro argument reuse in ddbridge-core aswell - one unbalanced braces around else in ddbridge-main, which is due to #ifdefs related to CONFIG_PCI_MSI, which preferrably should be kept as-is for readability.
