Subject: [PATCH 23/32] media: ipu6: isys: 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:
./pci/intel/ipu6/ipu6-isys-csi2.c:91:22-29: WARNING: Consider using %pe to print PTR_ERR()
