When building arm64 allyesconfig:
drivers/net/ipa/ipa_endpoint.c: In function 'ipa_endpoint_stop_rx_dma':
drivers/net/ipa/ipa_endpoint.c:1274:13: error: 'IPA_ENDPOINT_STOP_RX_SIZE'
undeclared (first use in this function)
drivers/net/ipa/ipa_endpoint.c:1274:13: note: each undeclared identifier is
reported only once for each function it appears in
drivers/net/ipa/ipa_endpoint.c:1289:2: error: implicit declaration of function
'ipa_cmd_dma_task_32b_addr_add' [-Werror=implicit-function-declaration]
drivers/net/ipa/ipa_endpoint.c:1291:45: error: 'ENDPOINT_STOP_DMA_TIMEOUT'
undeclared (first use in this function)
drivers/net/ipa/ipa_endpoint.c: In function 'ipa_endpoint_stop':
drivers/net/ipa/ipa_endpoint.c:1309:16: error: 'IPA_ENDPOINT_STOP_RX_RETRIES'
undeclared (first use in this function)
These functions were removed in a series, merged in as
commit 33395f4a5c1b ("Merge branch 'net-ipa-kill-endpoint-stop-workaround'").
Remove them again so that the build works properly.
