cfi_intelext_is_locked() misses get_chip()/put_chip() calls

[Ronald Wahl]

Hi,

cfi_intelext_is_locked() in cfi_cmdset_0001.c calls 
do_getlockstatus_oneblock() withou calling get_chip() before and 
put_chip() afterwards. So chip state is changed without protection.
This may lead to hanging processes.

Is this analysis correct?

If someone can fix this quickly - fine - but I can also provide a patch.

greets,
ron
