[PATCH] scsi: aic7xxx: use kmemdup

[Chen Zhou]

Fix memdup.cocci warnings:
./drivers/scsi/aic7xxx/aic79xx_core.c:9445:27-34: WARNING opportunity for kmemdup

Use kmemdup rather than duplicating its implementation.

[PATCH] [SCSI] aic7xxx: use kmemdup

[Muhammad Falak R Wani]

Use kmemdup when some other buffer is immediately copied into allocated
region. It replaces call to allocation followed by memcpy, by a single
call to kmemdup.
