Subject: Re: [PATCH 12/32] media: i2c: max9286: Use %pe format specifier

Quoting Ricardo Ribalda (2025-10-13 15:14:52)
> 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:
> ./i2c/max9286.c:755:7-14: WARNING: Consider using %pe to print PTR_ERR()
