Subject: qla3xxx: fix warning in drivers/net/qla3xxx.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=be5a3c62c805878d67036b4683f09118cab4c9fd;p=linux-beck.git

qla3xxx: fix warning in drivers/net/qla3xxx.c

this warning:

  drivers/net/qla3xxx.c: In function ‘ql3xxx_probe’:
  drivers/net/qla3xxx.c:3912: warning: ‘pci_using_dac’ may be used uninitialized in this function

triggers because GCC does not recognize the (correct) error flow
between 'pci_using_dac' and 'err'.

Annotate it.
