Subject: [trivial patch] scsi/ultrastor: clean up inline asm warnings
Hi,
Compiling latest mainline with gcc 4.2.1 spews the following warnings:
drivers/scsi/ultrastor.c: In function 'find_and_clear_bit_16':
drivers/scsi/ultrastor.c:303: warning: matching constraint does not allow a register
drivers/scsi/ultrastor.c:302: warning: matching constraint does not allow a register
drivers/scsi/ultrastor.c: At top level:

The following patch fixes it by using the '+' operator on the (*field)
operand, marking it as read-write to gcc. I diffed the two resulting .s,
and gcc produced the same code. This was tested with gcc 4.2.1 and gcc 3.4.3
