Revision 8902b10787c5a6e939c7adfe908c72404196052a authored by Chen Gang on 09 May 2014, 01:19:39 UTC, committed by Guan Xuetao on 20 June 2014, 00:22:39 UTC
The direct cause is IRQ_SPI is already defined as a macro in unicore32 architecture (also, blackfin and mips architectures define it). The related error (unicore32 with allmodconfig) CC [M] drivers/scsi/mvsas/mv_94xx.o In file included from drivers/scsi/mvsas/mv_94xx.c:27: drivers/scsi/mvsas/mv_94xx.h:176: error: expected identifier before numeric constant And IRQ_SAS_A and IRQ_SAS_B are used as 'u32' (although "enum pci_interrupt_cause" is not used directly, now). All together, need add 'MVS_' for "enum pci_interrupt_cause".
