misc: cb710: Fix a NULL vs IS_ERR() check in probe()

2025-11-26T14:09:34+00:00

The pcim_iomap_region() function never returns NULL, it returns error pointers. Update the checking to match.

cb710: avoid NULL pointer subtraction

misc: cb710: sgbuf2: Add missing documentation for cb710_sg_dwiter_write_next_block()'s 'data' arg

cb710/core.c: use generic power management

2020-06-29T16:43:42+00:00

Drivers should not use legacy power management as they have to manage power states and related operations, for the device, themselves. This driver was handling them with the help of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), etc. With generic PM, all essentials will be handled by the PCI core. Driver needs to do only device-specific operations. Compile-tested only.

misc: remove redundant 'default n' from Kconfig-s

2019-05-24T16:00:41+00:00

'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...
