staging: nvec: fix block comment style in nvec_interrupt()

2026-02-24T18:11:42Z

Fix multi-line block comment to use the preferred kernel comment style with leading asterisks on each line and a trailing */ on a separate line, as reported by checkpatch.pl.

staging: nvec: propagate error codes in tegra_nvec_probe()

2026-02-23T14:44:44Z

Several error paths in tegra_nvec_probe() return -ENODEV instead of propagating the actual error code from the called function. This prevents probe deferral from working correctly when a dependency (clock, IRQ) is not yet available. Fix this for platform_get_irq(), devm_clk_get(), and devm_request_irq() by propagating their return values. Use dev_err_probe() for the latter two to suppress log messages during deferred probing. The remaining -ENODEV returns for missing device tree node and slave-addr property are left unchanged as those are permanent configuration errors unrelated to probe deferral.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

staging: nvec: apply udelay only after the first byte has been sent

2026-01-11T12:53:56Z

Due to a HW bug in the Tegra20 SoC a udelay needs to be added after the first byte has been sent to the EC (I2C master). Move it to the correct position and add a comment that it should not be replaced by usleep_range.

The NVEC_PS2_DEBUG macro and NVEC_PHD() are unused and only add clutter. Remove them completely. Suggested-by: Greg Kroah-Hartman Signed-off-by: Emre Cecanpunar Link: https://patch.msgid.link/20251019095057.5684-1-emreleno@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: nvec: Fix incorrect null termination of battery manufacturer

2025-07-24T09:29:57Z

The battery manufacturer string was incorrectly null terminated using bat_model instead of bat_manu. This could result in an unintended write to the wrong field and potentially incorrect behavior. fixe the issue by correctly null terminating the bat_manu string.

staging: Switch back to struct platform_driver::remove()

2024-10-09T09:54:53Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all staging drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

staging: nvec: Use IRQF_NO_AUTOEN flag in request_irq()

disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.

staging: nvec: Capitalize outputs to match the rest of the driver

2024-07-31T06:19:09Z

Noticing that some messages were capitalized and some weren't, I capitalized them to match the rest. This makes the messages relatively easier to understand for an end user, and reduces confusion about capitalization. A comment was also capitalized.
