           Summary: s3c2440_clk_add disables inactive clocks
           Product: Platform Specific/Hardware
           Version: 2.5
     KernelVersion: 2.6.22
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: ARM
        AssignedTo: rmk at arm.linux.org.uk
        ReportedBy: alec_tsai at openmoko.com


Problem Description:

If we add the sanity check
    BUG_ON(!clk->usage);
before
    if ((--clk->usage) == 0)
in arch/arm/plat-s3c24xx/clock.c:clk_disable, this check gets triggered
by the two calls to clk_disable in
arch/arm/mach-s3c2440/clock.c:s3c2440_clk_add
