From da365772c4b66f5837222220349e32c73e62648c Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 28 Oct 2020 14:41:44 -0500 Subject: [PATCH] net: ipa: assign proper packet context base At the end of ipa_mem_setup() we write the local packet processing context base register to tell it where the processing context memory is. But we are writing the wrong value. The value written turns out to be the offset of the modem header memory region (assigned earlier in the function). Fix this bug.
