so when I run this through checkpatch --strict, then I get tons of warning that we have DOS style ^M line breaks. There are also trailing whitespace that need fixing. I can use cleanpatch to do this, but so can you.

Even after doing that there are still obvious plain coding style violation in the patch. For example:

ERROR: space prohibited before that ',' (ctx:WxW)
#610: FILE: drivers/bluetooth/nokia_core.c:517:
+			__h4p_set_auto_ctsrts(info, 0 , UART_EFR_RTS);
 			                              ^

CHECK: Alignment should match open parenthesis
#662: FILE: drivers/bluetooth/nokia_core.c:569:
+		h4p_outb(info, UART_OMAP_SCR,
+			     h4p_inb(info, UART_OMAP_SCR) |

CHECK: Blank lines aren't necessary before a close brace '}'
#692: FILE: drivers/bluetooth/nokia_core.c:599:
+
+}

These are only few. They are more and all these need fixing before I even consider it.

Also this worries me:

WARNING: DT compatible string "brcm,uart,bcm2048" appears un-documented -- check ./Documentation/devicetree/bindings/
#1222: FILE: drivers/bluetooth/nokia_core.c:1129:
+	{ .compatible = "brcm,uart,bcm2048" },

Regards

Marcel
