From: Olliver Schinagl Date: Tue, 30 Aug 2022 19:25:25 +0000 (+0200) Subject: realtek: Whitespace and codestyle cleanup X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=758c88b969639d0e6b684669d2e54dd1be3102f4;p=openwrt%2Fstaging%2Flinusw.git realtek: Whitespace and codestyle cleanup Fix some ugly whitepsaces and codestyle issues around the realtek sources. While this is by no means perfect, it catches what it caught.
