+Subject: [PATCH] brcmfmac: enlarge buffer size of caps to 512 bytes
+
+The buffer size of return of cap iovar is greater than 256 bytes in some
+firmwares. For instance, the return size of cap iovar is 271 bytes in 4373
+13.10.246.79 firmare. It makes feature capability parsing failed because
+caps buffer is default value.
+So we enlarge caps buffer size to 512 bytes and add the error print for
+cap iovar error.

+Subject: [PATCH] brcmfmac: Fix check for ISO3166 code
+
+The commit "regulatory: add NUL to request alpha2" increases the length of
+alpha2 to 3. This causes a regression on brcmfmac, because
+brcmf_cfg80211_reg_notifier() expect valid ISO3166 codes in the complete
+array. So fix this accordingly.
