Subject: Eliminate use of a kernel scsi header file.
X-Git-Tag: 1_00_pre8~54
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7495b0d4b1959b1391c460f24c285b46417730ea;p=oweals%2Fbusybox.git

Eliminate use of a kernel scsi header file.

Prevent potentially misaligned accesses while indexing a pointer
to the partition table, which would be a bad thing on i.e. arm.
