Subject: [PATCH next] soc: qcom: llcc-qcom: Fix NULL vs IS_ERR() bug in qcom_llcc_get_fw_config()
Date: Wed, 20 May 2026 09:00:30 +0300	[thread overview]
Message-ID: <ag1N_rAHEQ1YJsa7@stanley.mountain> (raw)

The devm_memremap() function doesn't return NULL, it returns error
pointers.  Fix the error checking to match.

Fixes: ac23106a9b9a ("soc: qcom: llcc-qcom: get SCT descriptors from fw-populated memory")
