Subject: [PATCH] ipmi_ssif: remove redundant null check on array client->adapter->name

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

The null check on client->adapter->name is redundant as name is an
array of I2C_NAME_SIZE chars and hence can never be null. We may as
well remove this redundant check.

Detected by CoverityScan, CID#1375918 ("Array compared against 0")
