clang with W=1 reports
sound/drivers/portman2x4.c:185:18: error: unused function
  'portman_read_command' [-Werror,-Wunused-function]
static inline u8 portman_read_command(struct portman *pm)
                 ^
sound/drivers/portman2x4.c:195:18: error: unused function
  'portman_read_data' [-Werror,-Wunused-function]

These static functions are not used, so remove them.
