moxtet: mark moxtet_bus_type as const

2024-01-04T16:01:14+00:00

Now that the driver core can properly handle constant struct bus_type,
move the moxtet_bus_type to be a constant structure as well, placing it
into read-only memory which can not be modified at runtime.

bus: moxtet: Add spi device table

2023-12-15T14:44:11+00:00

The moxtet module fails to auto-load on. Add a SPI id table to
allow it to do so.

bus: moxtet: Mark the irq as shared

2023-12-15T14:44:11+00:00

The Turris Mox shares the moxtet IRQ with various devices on the board,
so mark the IRQ as shared in the driver as well.

Without this loading the module will fail with:
  genirq: Flags mismatch irq 40. 00002002 (moxtet) vs. 00002080 (mcp7940x)

spi: make remove callback a void function

2022-02-09T13:00:45+00:00

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

bus: moxtet: fix potential stack buffer overflow

2020-02-15T18:33:19+00:00

The input_read function declares the size of the hex array relative to
sizeof(buf), but buf is a pointer argument of the function. The hex
array is meant to contain hexadecimal representation of the bin array.

bus: moxtet: fix unsigned comparison to less than zero

2019-09-04T15:30:16+00:00

Currently the size_t variable res is being checked for
an error failure however the unsigned variable is never
less than zero so this test is always false. Fix this by
making variable res ssize_t
