Subject: firewire: ohci: propagate return code from soft_reset to probe and resume
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a354cf00c71390c46927335fe20b65f38a528b59;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

firewire: ohci: propagate return code from soft_reset to probe and resume

software_reset() may fail
  - due to unresponsive chip with -EBUSY (-16), or
  - due to ejected or unseated card with -ENODEV (-19).
Let the PCI probe and resume routines log the actual error code instead
of hardwired -EBUSY.
