• d40657752   watchdog: sbc_fitpc2_wdt, fix crash on systems without DMI_BOARD_NAME ... Browse Code »

  Some systems don't provide DMI_BOARD_NAME in their DMI tables. Avoid
  crash in such situations in fitpc2_wdt_init.

  The fix is to check if the dmi_get_system_info return value is NULL.

  The oops:

  The mdelay function was used between I/O access commands, that causes peak
  in CPU usage. Fix it by substitution mdelay to msleep.

  Expand usage on fitPC2 compatible boards according to DMI identification.
