Author: delphij Date: Thu Nov 14 18:53:17 2013 New Revision: 258140 URL: http://svnweb.freebsd.org/changeset/base/258140 Log: The previous code makes a memory allocation in size of struct mbx_common_read_write_flashrom plus 32KB and caps the actual transfer size at 32KB. This is harmless as it is but may confuse static code analyzer, so allocate a full 32KB instead.
