6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Elder <elder@xxxxxxxxxx>
[ Upstream commit 37f0205538baf70beb57cdcb6c7d14aa13257926 ]
The width of the R_LENGTH field of the EV_CH_E_CNTXT_1 GSI register
is 24 bits (not 20 bits) starting with IPA v5.0. Fix this.
Fixes: faf0678ec8a0 ("net: ipa: add IPA v5.0 GSI register definitions")
