Subject: [PATCH 32/32] media: staging/ipu7: Use %pe format specifier

The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR().

This patch fixes this cocci report:
./ipu7/ipu7-isys-csi-phy.c:311:23-30: WARNING: Consider using %pe to print PTR_ERR()
./ipu7/ipu7-isys-csi2.c:59:22-29: WARNING: Consider using %pe to print PTR_ERR()

Signed-off-by: Ricardo Ribalda <ribalda@...omium.org>
