From: Christian Lamparter <chunkeey@...il.com>

commit 27d8d2d7a9b7eb05c4484b74b749eaee7b50b845 upstream.

There are two poly_store, but one should have been poly_show.

|adma.c:4382:16: error: conflicting types for 'poly_store'
| static ssize_t poly_store(struct device_driver *dev, const char *buf,
|                ^~~~~~~~~~
|adma.c:4363:16: note: previous definition of 'poly_store' was here
| static ssize_t poly_store(struct device_driver *dev, char *buf)
|                ^~~~~~~~~~
