SubjectPatch prefix guidelines
Question specifically to other maintainers, do we have a preferred patch prefix
rule set?

To date I try to use a subsystem prefix (with slashes) when a patch updates
multiple drivers or the subsystem Kconfig files,. e.g.

platform/x86: Drop duplicate dependencies on X86

(but I also see things like "platform: x86:")

When a specific driver is involved, I prefer to mention that specific file (or a
subset of the affected files). For example:

intel-hid: Remove duplicated acpi_remove_notify_handler

However, a patch just landed for a particular file that I have not managed a
patch for since I've maintained platform-drivers-x86. Its history is horribly
inconsistent:

$ git log --oneline --no-decorate drivers/platform/x86/intel_pmic_gpio.c
3769a89 platform: x86: intel-pmic: use gpiochip data pointer
58383c7 gpio: change member .dev to .parent
3493f41 platform: x86: drop owner assignment from platform_drivers
88d5e52 driver:gpio remove all usage of gpio_remove retval in driver
21a3542 platform-drivers-x86: intel_pmic_gpio: Fix off-by-one valid offset range
check
fef8ce16 x86 platform drivers: fix gpio leak
b859f15 Drivers: platform: x86: remove __dev* attributes.
9a2ffd1 intel_pmic_gpio: Convert printks to pr_<level>
21a8d02 x86 platform drivers: Build fix for intel_pmic_gpio
65d7ac03 platform-drivers: x86: pmic: Restore the dropped buslock/unlock
dced35a drivers: Final irq namespace conversion
98401ae platform-drivers: x86: pmic: Use request_irq instead of chained handler
d4b7de6 platform-drivers: x86: pmic: Use irq_chip buslock mechanism
cb8e5e6 platform-drivers: x86: Convert pmic to new irq_chip functions
180e9d1 platform-drivers: x86: pmic: Fix up bogus irq hackery
456dc30 [PATCH] intel_pmic_gpio: modify EOI handling following change of kernel
irq subsystem
61d8e11 Remove duplicate includes from many files
4119617 intel_pmic_gpio: fix off-by-one value range checking
ffcfff3 intel_pmic_gpio: swap the bits and mask args for
intel_scu_ipc_update_register
8950778 gpio: Add PMIC GPIO block support

I don't want to impose arbitrary rules on my contributors, nor do I want to
contribute to an inconsistent git log. In this case, my default would be to
apply the incoming patch (which touches only the one file) as:

intel_pmic_gpio: Make explicitly non-modular

Thoughts? Preferences?
