[PATCH net-next v2 1/5] net: ipa: head-of-line block registers are RX only

From: Alex Elder
Date: Tue Jun 30 2020 - 09:33:17 EST


The INIT_HOL_BLOCK_EN and INIT_HOL_BLOCK_TIMER endpoint registers
are only valid for RX endpoints.

Have ipa_endpoint_modem_hol_block_clear_all() skip writing these
registers for TX endpoints.

v2: The commented calls to assert() that were added are now gone.
