From 4aa3e48d2e09424449b2e0f2d5581388ba9e261b Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 12 Apr 2021 16:00:26 +0000 Subject: [PATCH] i2c: mpc: drop release for resource allocated with devm_* It's not necessary to release resource which allocated with devm_* and those release may leads to a double free. And also remove useless irq_dispose_mapping() call since mapping not created.
