Subject: [PATCH] Check patch reports multiple var with a function assignment

Running checkpatch.pl products an warning when it should not.  I believe 
it can be fixed by adding to the regular expression, but feel free to 
fix it another way as I may not know all the cases this is trying to catch.

-- check patch output --
WARNING: declaring multiple variables together should be avoided
#451: FILE: drivers/serial/8250.c:1685:
+       unsigned char lsr = serial_inp(up, UART_LSR);

-- end check patch output --
