daemon.c: refactor hostinfo_init() to HOSTINFO_INIT macro

avar · gitster · commit 6e54a32468e2 · 2021-09-27T15:02:32.000-07:00
Remove the hostinfo_init() function added in 01cec54 (daemon: deglobalize hostname information, 2015-03-07) and instead initialize the "struct hostinfo" with a macro. This is the more idiomatic pattern in the codebase, and doesn't leave us wondering when we see the *_init() function if this struct needs more complex initialization than a macro can provide.
