Subject: linux-next: build failure after merge of the thermal tree

Hi Zhang,

After merging the thermal tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/thermal/cpu_cooling.c: In function 'get_idr':
drivers/thermal/cpu_cooling.c:89:14: error: 'MAX_ID_MASK' undeclared (first use in this function)

Caused by commit 023614183768 ("thermal: add generic cpufreq cooling
implementation") interacting with commit 125c4c706b68 ("idr: rename
MAX_LEVEL to MAX_IDR_LEVEL") which very recently entered Linus' tree.

I have applied the following fix patch for today:
