[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.11-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")
