commit 7bb9b06ac44dfd0189cf58d6564bfc890cc10e9c Author: Sven Eckelmann sven@narfation.org Date: Thu Oct 31 17:34:37 2019 +0100
batman-adv: Use 'fallthrough' pseudo keyword
The usage of the '/* fall through */' comments in switches are no longer marked as non-deprecated variant of implicit fall throughs for switch statements. The commit 294f69e662d1 ("compiler_attributes.h: Add 'fallthrough' pseudo keyword for switch/case use") introduced a replacement keyword which should be used instead.
