6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
[ Upstream commit 3727c0b4ff6ba0e61203544b4c831f7f8899753b ]
For all of the devices regmap IRQ may try to created the folder
with the same name which is impossible and fails with:
debugfs: File '\_SB.IPC1.PMIC' in directory 'domains' already present!
Add domain_suffix to all of the IRQ chips driver registers to solve
the issue.
Fixes: 39d047c0b1c8 ("mfd: add Intel Broxton Whiskey Cove PMIC driver")
Fixes: 957ae5098185 ("platform/x86: Add Whiskey Cove PMIC TMU support")
Fixes: 57129044f504 ("mfd: intel_soc_pmic_bxtwc: Use chained IRQs for second level IRQ chips")
Depends-on: dde286ee5770 ("regmap: Allow setting IRQ domain name suffix")
