From: Alex Elder Date: Wed, 28 Oct 2020 19:41:44 +0000 (-0500) Subject: net: ipa: assign proper packet context base X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=279dc955745a6800911404fe375686626aa7fed3;p=linux.git 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.
