Subject: [PATCH net-next 1/7] net: ipa: kill struct ipa_interconnect
Date:   Fri,  4 Feb 2022 13:50:38 -0600
Message-Id: <20220204195044.1082026-2-elder@linaro.org>

The ipa_interconnect structure contains an icc_path pointer, plus an
average and peak bandwidth value.  Other than the interconnect name,
this matches the icc_bulk_data structure exactly.

Use the icc_bulk_data structure in place of the ipa_interconnect
structure, and add an initialization of its name field.  Then get
rid of the now unnecessary ipa_interconnect structure definition.
