mISDN: hfcmulti: use __iomem address space modifier
Impact: make use of the __iomem address space modifier, and change u_char *, u_short * and u_int * to void * Fix more than 30 sparse warnings of this or similar type: drivers/isdn/hardware/mISDN/hfcmulti.c:261:31: warning: incorrect type in argument 2 (different address spaces) drivers/isdn/hardware/mISDN/hfcmulti.c:261:31: got unsigned char [usertype] * drivers/isdn/hardware/mISDN/hfcmulti.c:261:31: expected void volatile [noderef] <asn:2>*addr Signed-off-by: Hannes Eder <hannes@hanneseder.net> Acked-by: Karsten Keil <kkeil@suse.de> Signed-off-by: David S.
