Subject[PATCH 2/8] clk: si5351: Delete an error message for a failed memory allocation in si5351_i2c_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 20 Apr 2017 07:34:54 +0200

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.
