* scsi: saner replacements for ->proc_info()Al Viro2013-04-091-9/+59
| | | | | | | | | | | | | | | | | It's still an obsolete interface; don't introduce those in new drivers. However, it's saner than the ->proc_info() and commits after this one will convert the existing ->proc_info() users to it. The read side is ->show_info(seq_file *, struct Scsi_Host *); use seq_... for generating contents. The write side is ->write_info(struct Scsi_Host *, char *, int). Again, this is driven by procfs needs; we are going to kill ->write_proc() and ->read_proc() and this is the main obstacle to burying that piece of shit.

The ixgbevf calls to pci_disable_msix() and to free the msix_entries memory should not occur if device open fails. Instead they should be called during device driver removal to balance with the call to pci_enable_msix() and the call to allocate msix_entries memory during the device probe and driver load. The remaining 4 of 5 igb patches are simple 1-3 line patches to fix several issues such as possible null pointer dereference, PHC stopping on max frequency, make sensor info static and SR-IOV initialization reordering.

| | * | igb: fix PHC stopping on max freqJiri Benc2013-03-261-1/+1

However, if this value is passed to igb_ptp_adjfreq_82576, incvalue overflows out of INCVALUE_82576_MASK, resulting in setting of zero TIMINCA.incvalue, stopping the PHC (instead of going at twice the nominal speed). Fix the advertised max_adj value to the largest value hardware can handle. As there is no min_adj value available (-max_adj is used instead), this will also prevent stopping the clock intentionally. It's probably not a big deal, other igb MAC types don't support stopping the clock, either.

The failing path is: igb_probe igb_sw_init if (max_vfs > 7) { adapter->vfs_allocated_count = 7; ... igb_probe_vfs igb_enable_sriov(, max_vfs) if (num_vfs > 7) { err = -EPERM; ... This leaves vfs_allocated_count = 7 and vf_data = NULL, so we bomb out when igb_probe finally calls igb_reset. It seems like a really bad idea, and somewhat pointless, to set vfs_allocated_count separate from vf_data, but limiting max_vfs is enough to avoid the null pointer.

The calls to pci_disable_msix() and to free the msix_entries memory should not occur if device open fails.
