Subject: [PATCH] staging: speakup: remove redundant initialization of pointer p_key

From: Colin Ian King <colin.king@...onical.com>

Pointer p_key is being initialized with a value that is never read,
it is assigned a new value later on. The initialization is redundant
and can be removed.

Addresses-Coverity: ("Unused value")
