Sparse complains of these: drivers/bus/hisi_lpc.c:82:38: warning: incorrect type in argument 1 (different address spaces) drivers/bus/hisi_lpc.c:82:38: expected void const volatile [noderef] <asn:2>*addr drivers/bus/hisi_lpc.c:82:38: got unsigned char * drivers/bus/hisi_lpc.c:131:35: warning: incorrect type in argument 1 (different address spaces) drivers/bus/hisi_lpc.c:131:35: expected unsigned char *mbase drivers/bus/hisi_lpc.c:131:35: got void [noderef] <asn:2>*membase drivers/bus/hisi_lpc.c:186:35: warning: incorrect type in argument 1 (different address spaces) drivers/bus/hisi_lpc.c:186:35: expected unsigned char *mbase drivers/bus/hisi_lpc.c:186:35: got void [noderef] <asn:2>*membase drivers/bus/hisi_lpc.c:228:16: warning: cast to restricted __le32 drivers/bus/hisi_lpc.c:251:13: warning: incorrect type in assignment (different base types) drivers/bus/hisi_lpc.c:251:13: expected unsigned int [unsigned] [usertype] val drivers/bus/hisi_lpc.c:251:13: got restricted __le32 [usertype] <noident>
Clean them up.
