Subject: [PATCH v2 1/5] power: Use %pe to print error pointers symbolically
Date: Sun, 13 Sep 2026 00:41:51 +0530 [thread overview]
Message-ID: <20260912191156.185448-2-sumeet4linux@gmail.com> (raw)
In-Reply-To: <20260912191156.185448-1-sumeet4linux@gmail.com>
Replace PTR_ERR() and %ld/%li with %pe and pass the original pointer
directly to dev_info(), dev_Warn and dev_dbg(). The %pe format specifier
prints a symbolic error name (e.g. -ENOMEM) when CONFIG_SYMBOLIC_ERRNAME
is enabled, otherwise it falls back gracefully and prints the raw integer
value. This makes messages more readable without any functional change.
