Subject: [PATCH 5/9] media/radio: fix rtrack2 CONFIG IO PORT

From: Randy Dunlap <rdunlap@...otime.net>

Modify radio-rtrack2 to use HEX_STRING(CONFIG_RADIO_RTRACK2_PORT)
so that the correct IO port value is used.

Fixes this error message when CONFIG_RADIO_RTRACK2_PORT=30c:
drivers/media/radio/radio-rtrack2.c:31:17: error: invalid suffix "c" on integer constant
