-Subject: [PATCH] drivers/macintosh: Fix memleak in windfarm_pm112 driver
-
-commit 93900337b9ac2f4eca427eff6d187be2dc3b5551 upstream.
-
-create_cpu_loop() calls smu_sat_get_sdb_partition() which does
-kmalloc() and returns the allocated buffer. In fact it's called twice,
-and neither buffer is freed.
-
-This results in a memory leak as reported by Erhard:
-  unreferenced object 0xc00000047081f840 (size 32):
-    comm "kwindfarm", pid 203, jiffies 4294880630 (age 5552.877s)

-Fix it by rearranging the logic so we deal with each buffer
-separately, which then makes it easy to free the buffer once we're
-done with it.
