Here is the environment cinfiguration: cpu - atom, sd card as bootabl…

…e disk, loist of devices:

/sys/block/zram0
/sys/block/mmcblk0boot0
/sys/block/mmcblk0boot1
/sys/block/mmcblk2
/sys/block/mmcblk0

Hardinfo got nex pathes for reading for the report:

1) # cat /sys/block/mmcblk0/device/oemid
0x0103
2) # cat /sys/block/mmcblk2/device/oemid
0x534d
3) # cat /sys/block/mmcblk0boot0/device/oemid
cat: /sys/block/mmcblk0boot0/device/oemid: No such file or directory
4) # cat /sys/block/mmcblk0boot1/device/oemid
cat: /sys/block/mmcblk0boot1/device/oemid: No such file or directory

In the code no checks if files from previous step for device was read and pointer not NULL:

gchar *oemid_path = g_strdup_printf("/sys/block/%s/device/oemid", e->d->block_dev);
gchar *manfid_path = g_strdup_printf("/sys/block/%s/device/manfid", e->d->block_dev);
gchar *oemid = NULL, *manfid = NULL;
g_file_get_contents(oemid_path, &oemid, NULL, NULL);
g_file_get_contents(manfid_path, &manfid, NULL, NULL);

unsigned int id = strtol(oemid, NULL, 16);
...
id = strtol(manfid, NULL, 16);

Before srttol need check for NULL
