    Fix mis-merge of intel_powerclamp.c resulting in compile error · 19cc90f5
    Linus Torvalds authored
    The new intel_powerclamp thermal cooling device driver was merged in
    commit 2af78448 (Pull thermal management updates from Zhang Rui)
    without any data conflicts.  But there was a more subtle conflict I
    missed: the driver uses MAX_USER_RT_PRIO, but commit 8bd75c77
    ("sched/rt: Move rt specific bits into new header file") had moved that
    define from <linux/sched.h> to <linux/sched/rt.h>.
    
    Which caused this build failure:
    
      drivers/thermal/intel_powerclamp.c: In function ‘clamp_thread’:
      drivers/thermal/intel_powerclamp.c:360:21: error: ‘MAX_USER_RT_PRIO’ undeclared (first use in this function)
      drivers/thermal/intel_powerclamp.c:360:21: note: each undeclared identifier is reported only once for each function it appears in
    
    And because I don't do a full "make allmodconfig" build after each pull,
    I didn't notice until too late.  So now the fix is here, separately from
    the merge commit.
