a=ed25519; pk=6C4wavGFy/OsR8yQQKNWuDXoYPHp2L3sfgNfyzTruTk= Use the %pe format specifier instead of %ld with PTR_ERR() for printing error pointers in various drivers across usb subsystem. This prints symbolic error names (e.g.-ENOMEM) instead of errno numbers (e.g. -12), making error logs more readable. Fix coccinelle reported warnings: WARNING: Consider using %pe to print PTR_ERR() Compile tested only.
