+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: Remove func0 from function array
+
+func0 is not provided by the mmc stack as a function when probing.
+Instead providing specific access functions to read/write it.
+
+This prepares for a patch to remove the actual array entry itself.

+Subject: [PATCH] brcmfmac: More efficient and slightly easier to read fixup

+
+Its more efficient to test the register we're interested in first,
+potentially avoiding two more comparisons, and therefore always avoiding
+one comparison per call on all other chips.

+From: Ian Molton <ian@mnementh.co.uk>
+Date: Tue, 19 Dec 2017 13:47:14 +0100
+Subject: [PATCH] brcmfmac: Clean up interrupt macros
+
+Make it more obvious that this code acually enables interrupts, and
+provide nice definitions for the bits in the register.
