commit b5e0cc2fa44f52f16fc0b9c3f1709bc0f43fe2d0 Author: Kyle Evans <[email protected]> AuthorDate: 2024-04-21 03:04:04 +0000 Commit: Kyle Evans <[email protected]> CommitDate: 2024-04-21 03:04:04 +0000 ahc(4): resolve some minor nits In ahc_init(), qoutfifo is already assigned to effectively the same value a couple lines up, except in the first assignment it uses the proper definition; keep the more descriptive assignment. ahc_targetcmd_offset() gets the offset wrong entirely; as per the area of ahc_init() this diff also touches, targetcmds is laid out first in the shared map and it's followed by the qoutfifo. As a result, we'd generally be getting negative offsets here. We can't actually do a partial sync anyways, so there was no consequence to getting this wrong.
