[PATCH v2 0/3] usb: Use %pe to print error pointers

Replace PTR_ERR() in format strings with 
%pe format specifier across the USB subsystem. %pe prints 
symbolic error names (e.g., -ENOMEM) instead of 
raw numbers (e.g., -12), making error logs more readable. 
These patches fix coccinelle reported warning: "Consider 
using %pe to print PTR_ERR()" in usb subsystem.

The patches are grouped by subsystem:
  1/3 - chipidea
  2/3 - miscellaneous USB drivers
  3/3 - typec

All patches are compile-tested on x86_64. Please let me know if 
any more testing is needed for any patch.
