Subject: [PATCH 2/8] clk: si5351: Delete an error message for a failed memory
 allocation in si5351_i2c_probe()

The script "checkpatch.pl" pointed information out like the following.

* CHECK: Comparison to NULL could be written "!drvdata"

  Thus adjust this expression.


* WARNING: Possible unnecessary 'out of memory' message

  Thus remove such a statement here.
