Subject: [PATCH] mt7615: Delete an error message in mt7622_wmac_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>

The function “platform_get_irq” can log an error already.
Thus omit a redundant message for the exception handling in the
calling function.

This issue was detected by using the Coccinelle software.
