The patch titled git-scsi-misc: aha152x: fix isa/pcmcia compile problem has been removed from the -mm tree. Its filename was aha152x-fix-isa-pcmcia-compile-problem.patch This patch was dropped because an updated version will be merged The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: git-scsi-misc: aha152x: fix isa/pcmcia compile problem From: Tejun Heo <htejun@xxxxxxxxx> aha152x.c is built twice - once for the isa driver and once for the PCMCIA one. Through #ifdefs, the compiled codes are slightly depending on which flavor is being built. This patch adds GLOBAL() macro to aha152x.h which changes the symbol depending on PCMCIA. This bug has always existed but has been masked by the fact the drivers/scsi/pcmcia used subdir-(y|m) instead of obj-(y|m) which made drivers/scsi/pcmcia/built_in.o not linked into the kernel and thus avoided the duplicate symbols during compilation.
