6.6-stable review patch. If anyone has any objections, please let me know.

From: Christophe JAILLET christophe.jaillet@wanadoo.fr
[ Upstream commit e6722ea6b9ed731f7392277d76ca912dfffca7ee ]
'pclk' is only used locally in the probe. Remove it from the 'synquacer_i2c' structure.
Also remove a useless debug message.
