Subject: staging: comedi: me_daq: pass on the error from comedi_pci_enable()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4ae76422338f25ee4907e92ae3cdc968fdd9b578;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: comedi: me_daq: pass on the error from comedi_pci_enable()

Instead of returning -EIO when comedi_pci_enable() fails, pass on
the actual error code. Also, remove the kernel noise when the
function fails.
