Subject: net: e1000: annotate switch/case fallthrough
X-Git-Tag: v2025.07-rc1~108^2~6
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=960d3d933dbda88aed6d4fcf0711dbc7448ffd83;p=pandora-u-boot.git

net: e1000: annotate switch/case fallthrough

The E1000 driver uses an implicit switch/case fallthrough for sharing
some code supporting different PHYs.

Add our "fallthrough;" statement-like macro before the two labels in
e1000_set_phy_type(), to avoid a warning when GCC's -Wimplicit-fallthrough
warning option is enabled.
