Subject: [RESEND][PATCH v1 1/9] mfd: intel_soc_pmic_crc: Use devm_regmap_add_irq_chip()
Date:   Mon, 18 Jul 2022 15:23:20 +0300
Message-Id: <20220718122328.8287-1-andriy.shevchenko@linux.intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use devm_regmap_add_irq_chip() to simplify the code.

While at it, replace -1 magic parameter by PLATFORM_DEVID_NONE when
calling mfd_add_devices().

Note, the mfd_add_devices() left in non-devm variant here due to
potentially increased churn while wrapping pwm_remove_table().
