+Subject: [PATCH] brcmfmac: Rename / replace old IO functions with simpler
+ ones.
+
+Primarily this patch removes:
+
+brcmf_sdiod_f0_writeb()
+brcmf_sdiod_reg_write()
+brcmf_sdiod_reg_read()
+
+Since we no longer use the quirky method of deciding which function to
+address via the address being accessed, take the opportunity to rename
+some IO functions more in line with common kernel code. We also convert
+those that map directly to sdio_{read,write}*() to macros.
