-Subject: [PATCH] brcmfmac: Limit memory allocs to <64K
-
-Some systems have problems with allocating memory allocation larger
-then 64K. Often on unload/load or suspend/resume a failure is
-reported: Could not allocate wiphy device. This patch makes the
-escan intermediate storage buf dynamically allocated, and smaller
-than 64K.
