BASH: troubke using a function argument passed to awk to find major

Hi,
I am a relative newbie to BASH programming but I've read and learned a
lot but I can't seem to solve my problem. I am trying to figure out the
major number of a device through cat /proc/devices piped to awk:

cat /proc/devices | awk '/theDeviceName/ { printf $1 }'.

I am trying to write a function that receives the device name as an
argument:

function find_major()
{
MAJOR=`cat /proc/devices | awk '/$1/ { printf $1 }'`

# do some other work...
}

I have tried this:
function find_major()
{
MAJOR=`cat /proc/devices | awk '/$1/ { printf \$1 }'`

# do some other work...
}

and some other alternatives but just can't seem to get it to work. Can
anyone help?

Thanks in advance!!
