gcc-6 and higher warn about the way some loops are written in
the ncr5380 driver:

drivers/scsi/g_NCR5380.c: In function 'generic_NCR5380_pread':
drivers/scsi/g_NCR5380.c:541:3: error: this 'while' clause does not guard... [-Werror=misleading-indentation]
   while (NCR5380_read(C400_CONTROL_STATUS_REG) & CSR_HOST_BUF_NOT_RDY);
   ^~~~~
drivers/scsi/g_NCR5380.c:544:3: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'while'

This was addressed in mainline kernels as part of a rework on commit
12150797 ("ncr5380: Use runtime register mapping"). We don't
want the entire patch backported to stable kernels, but we can
backport one hunk to get rid of the warning.
