[PATCH net 3/4] net: ipa: use the right accessor in ipa_endpoint_status_skip()

From: Alex Elder
Date: Mon Feb 01 2021 - 18:28:54 EST


When extracting the destination endpoint ID from the status in
ipa_endpoint_status_skip(), u32_get_bits() is used. This happens to
work, but it's wrong: the structure field is only 8 bits wide
instead of 32.

Fix this by using u8_get_bits() to get the destination endpoint ID.
