staging: most: dim2: replace BUG_ON() in poison_channel()

2026-03-31T08:46:39Z

Replace BUG_ON() range check on ch_idx with a return of -EINVAL. BUG_ON() is deprecated as it crashes the entire kernel on assertion failure (see Documentation/process/deprecated.rst).

staging: most: dim2: replace BUG_ON() in try_start_dim_transfer()

2026-03-31T08:46:38Z

Replace BUG_ON() calls with graceful error handling. For the null/uninitialized channel checks, return -EINVAL instead of crashing the kernel. For the zero bus_address check, release the spinlock and return -EFAULT. BUG_ON() is deprecated as it crashes the entire kernel on assertion failure (see Documentation/process/deprecated.rst).

staging: most: fix typos in driver_usage.txt

2026-03-09T16:50:13Z

Fix spelling mistakes in driver_usage.txt documentation: - 'can by used' should be 'can be used' - 'config itmes' should be 'config items' - 'isochrnous' should be 'isochronous' - 'packts_per_xact' should be 'packets_per_xact' Signed-off-by: Mustafa Karamanli Link: https://patch.msgid.link/20260309055836.3741-1-mbarancemkaramanli@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: most: dim2: replace ROUND_UP_TO macro with round_up()

2026-03-09T16:49:36Z

The ROUND_UP_TO macro reuses argument 'd', which can cause unintended side effects. Remove it and replace the macro call with the existing round_up() function.

staging: most: dim2: remove unnecessary string indirection in dev_err

2026-02-25T15:03:40Z

Replace dev_err(&pdev->dev, "%s\n", "clk_prepare_enable failed") with the direct format string dev_err(&pdev->dev, "clk_prepare_enable failed\n"). The extra level of indirection through %s is unnecessary. Signed-off-by: Artem Lytkin Link: https://patch.msgid.link/20260224180750.28468-4-iprintercanon@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: most: dim2: use dev_err_probe and proper error codes for clock

2026-02-25T15:03:40Z

Replace hardcoded -EFAULT returns with dev_err_probe() and PTR_ERR() when devm_clk_get() fails in fsl_mx6_enable(). This ensures the correct error code is propagated (e.g. -EPROBE_DEFER for deferred probing) and avoids log noise during probe deferral.

staging: most: dim2: replace IS_ERR_OR_NULL with IS_ERR for devm_clk_get

2026-02-25T15:03:40Z

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().
