Subject: [RFC V2 3/6] sh/mm: Stop using pte_ERROR()
Date: Tue, 11 Aug 2026 09:51:16 +0530 [thread overview]
Message-ID: <20260811042119.3652929-4-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20260811042119.3652929-1-anshuman.khandual@arm.com>
Directly use pr_err() in set_pte_phys() and drop pte_ERROR() which helps in
eventually dropping pte_ERROR() macro across the tree. In this new printing
__FILE__ and __LINE__ has been dropped because they are always the same and
don't really add any value.
