drivers: misc: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

2026-10-01T12:01:57+00:00

Convert the deprecated SIMPLE_DEV_PM_OPS
to DEFINE_SIMPLE_DEV_PM_OPS
and pm_sleep_ptr().

This lets us drop the __maybe_unused annotations
from the suspend and resume callbacks,
also reduces kernel size in case CONFIG_PM or
CONFIG_PM_SLEEP is disabled.

Also allow to remove #ifdef CONFIG_PM_SLEEP.

misc: Unify code style for various *_device_id arrays

2026-07-31T12:20:50+00:00

 - Add a trailing comma for initializers unless the closing brace is on
   the same line and for the list terminator;
 - Use a single space in the list terminator;
 - A space after an opening { and before a closing };
 - Use the PCI_DEVICE* macro in two drivers for pci_device_id entry
   which is usual for these arrays
 - No explicit zeros in the list terminator;

None of these changes introduces changes to the compiled result.

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

2021-10-05T13:50:05+00:00

clang-14 complains about an unusual way of converting a pointer to
an integer:

drivers/misc/cb710/sgbuf2.c:50:15: error: performing pointer subtraction with a null pointer has undefined behavior [-Werror,-Wnull-pointer-subtraction]
        return ((ptr - NULL) & 3) != 0;

Replace this with a normal cast to uintptr_t.

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

2020-06-29T16:45:53+00:00

An attempt was made to provide a proper kerneldoc header for
cb710_sg_dwiter_write_next_block(), but a description for it's 'data'
argument was missed.

Squashes W=1 kernel build warning:

 drivers/misc/cb710/sgbuf2.c:131: warning: Function parameter or member 'data' not described in 'cb710_sg_dwiter_write_next_block'

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.
