Subject: include/compiler.h: remove redundant declaration of errno
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9312bba01a41191f20821b66b84b3ff1d2902e8a;p=u-boot.git

include/compiler.h: remove redundant declaration of errno

Commit 37566090 "compiler.h: unify system ifdef cruft here" added both
a "#include <errno.h>" and a "extern int errno;" to include/compiler.h
which is causing build warnings for some systems, for example for the
"netstar" board:

	In file included from /home/wd/git/u-boot/work/lib/crc32.c:15:
	include/compiler.h:28: warning: function declaration isn't a prototype

The declaration of "errno" should be redundant, as <errno.h> is
supposed to provide a correct declaration, so drop it.
