From 0c1aa20fb87b796d904f4d89ad12e5a0c483127b Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Thu, 29 May 2008 22:39:28 +1000 Subject: [PATCH] [netdrvr] Fix 8390 build breakage From: tony@bakeyournoodle.com (Tony Breeds) The commit 3f8cb098859bbea29d7b3765a3102e4a6bf81b85 (drivers/net/lib8390: fix warning, trim trailing whitespace) removed ei_local from ei_tx_err() and ei_rx_overrun() resulting in the following build errors on m68k and sh: Using /scratch1/tony/next as source for kernel GEN /scratch1/tony/next_out/Makefile CHK include/linux/version.h CHK include/linux/utsrelease.h CALL /scratch1/tony/next/scripts/checksyscalls.sh CHK include/linux/compile.h CC [M] drivers/net/zorro8390.o In file included from /scratch1/tony/next/drivers/net/zorro8390.c:47: drivers/net/lib8390.c: In function 'ei_tx_err': drivers/net/lib8390.c:556: error: 'ei_local' undeclared (first use in this function) drivers/net/lib8390.c:556: error: (Each undeclared identifier is reported only once drivers/net/lib8390.c:556: error: for each function it appears in.) drivers/net/lib8390.c: In function 'ei_rx_overrun': drivers/net/lib8390.c:823: error: 'ei_local' undeclared (first use in this function) make[3]: *** [drivers/net/zorro8390.o] Error 1 make[2]: *** [drivers/net] Error 2 make[1]: *** [drivers] Error 2 make: *** [sub-make] Error 2 The problem is that ei_inb_p() is using various #defines (from drivers/net/8390.h) that use EI_SHIFT, which in some drivers on some architectures use ei_local. Tag ei_local as "__maybe_unused" to keep it around and keep the warnings the original commit is trying to silence ... silenced.
