X-Git-Tag: v6.19-rc1~87^2~26
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d51b09a0feb63029be64226502cbcf53adc434b0;p=thirdparty%2Fkernel%2Flinux.git

EDAC/ie31200: #undef field_get() before local definition

Prepare for the advent of a globally available common field_get() macro
by undefining the symbol before defining a local variant.  This prevents
redefinition warnings from the C preprocessor when introducing the common
macro later.
