[PATCH 0/2] staging: most: dim2: fix error handling in fsl_mx6_enable

[PATCH 0/2] staging: most: dim2: fix error handling in fsl_mx6_enable

[Artem Lytkin]

Fix error handling issues in fsl_mx6_enable() in the DIM2 driver.

Patch 1 fixes a real bug: the return value of clk_prepare_enable()
for the PLL clock is not checked, while the same call for the MLB
clock is properly checked earlier in the function.

Patch 2 addresses review feedback from Dan Carpenter on an earlier
attempt to fix this function [1]: replace IS_ERR_OR_NULL() with
IS_ERR(), use dev_err_probe() to propagate actual error codes and
handle probe deferral correctly.

[PATCH 1/2] staging: most: dim2: check return value of clk_prepare_enable for PLL

[Artem Lytkin]

The return value of clk_prepare_enable() for the PLL clock is not
checked, while the same call for the MLB clock is properly checked
earlier in the function. If clk_prepare_enable() fails, the driver
continues without the PLL clock enabled, leading to undefined
hardware behavior.

Add the missing error check and disable the MLB clock on failure to
keep the cleanup consistent with the rest of the function.

[PATCH 2/2] staging: most: dim2: fix error handling in fsl_mx6_enable

[Artem Lytkin]

Address several error handling issues in fsl_mx6_enable():

- Replace IS_ERR_OR_NULL() with IS_ERR() for devm_clk_get() return
  value checks, since devm_clk_get() never returns NULL on error.

- Replace hardcoded -EFAULT returns with dev_err_probe() which both
  propagates the actual error code from devm_clk_get() and suppresses
  log messages during probe deferral.

- Remove an unnecessary string indirection in the clk_prepare_enable
  error message.

Some of these are unrelated things.

[PATCH v2 0/3] staging: most: dim2: clean up error handling in fsl_mx6_enable

[Artem Lytkin]

This series cleans up error handling in fsl_mx6_enable(), split into
separate logical changes per Dan Carpenter's review of v1.

Changes since v1:
  - Split combined patch into 3 separate patches (one change per patch)
  - Extended string indirection fix to all three enable functions

Patch 1 replaces IS_ERR_OR_NULL() with IS_ERR() since devm_clk_get()
never returns NULL.

Patch 2 replaces dev_err() + hardcoded -EFAULT with dev_err_probe()
and PTR_ERR() to propagate correct error codes and handle probe
deferral properly.

Patch 3 removes unnecessary string indirection in dev_err() calls
("%s\n", "message" -> "message\n").

devm_clk_get() never returns NULL, so IS_ERR_OR_NULL() checks are
unnecessary. Replace them with IS_ERR() for both the "mlb" and
"pll8_mlb" clock lookups in fsl_mx6_enable().

I see 2 different copies of this series, as can be seen on
lore.kernel.org:
	https://lore.kernel.org/all/20260224043723.1828-1-iprintercanon@gmail.com/

which is "correct"?

Can you send a v3 so I know what to do?

[PATCH net-next 0/2] net: phy: add Rust reference driver for ET1011C

[Artem Lytkin]

This series adds a Rust reference driver for the LSI ET1011C PHY,
following the pattern established by the existing Rust Asix PHY driver
(ax88796b_rust.rs).

Patch 1 exposes genphy_config_aneg() in the Rust PHY abstraction,
which is needed by PHY drivers that perform custom BMCR configuration
before calling the generic auto-negotiation setup.

Patch 2 adds the Rust ET1011C driver itself, implementing config_aneg
and read_status callbacks. It is a feature-equivalent port of the C
driver at drivers/net/phy/et1011c.c.
