+Subject: dmidecode: Use read_file() to read the DMI table from sysfs
+
+We shouldn't use mem_chunk() to read the DMI table from sysfs. This
+will fail for SMBIOS v3 implementations which specify a maximum length
+for the table rather than its exact length. The kernel will trim the
+table to the actual length, so the DMI file will be shorter than the
+length announced in entry point.
+
+read_file() fits the bill in this case, as it deals with end of file
+nicely.
+
+This also helps with corrupted DMI tables, as the kernel will not
+export the part of the table that it wasn't able to parse, effectively
+trimming it.
+
+This fixes bug #46176:
+https://savannah.nongnu.org/bugs/?46176
+Unexpected end of file error
