[PATCH v2 1/2] mfd: sec-core: Remove duplicated device type from sec_pmic_dev

[PATCH v2 1/2] mfd: sec-core: Remove duplicated device type from sec_pmic_dev

[Krzysztof Kozlowski]

The device type was stored in sec_pmic_dev state container twice:
 - unsigned long type (initialized from of_device_id or i2c_device_id)
 - int device_type (initialized as above or from board files when there
   is no DTS)

The 'type' field was never used outside of probe so it can be safely
removed.

Change also the device_type in sec_pmic_dev and sec_platform_data to
unsigned long to avoid any casts.

Changes since v1:
 - Change device_type field of sec_platform_data from int to unsigned long.
 - Update commit msg.

What upstream commit are these patches based on? They don't seem to
apply to v3.15-rc2. Could you rebase and resend with my Ack applied
please?

They depend on this:
mfd/rtc: s5m: Do not allocate RTC I2C dummy and regmap for unsupported chipset
https://lkml.org/lkml/2014/4/14/50

Which I thought you applied with Alessandro ack. However this was picked
up also by Andrew Morton:
http://git.cmpxchg.org/cgit/linux-mmots.git/log/

I will rebase them but still this would produce a (rather simple) merge
conflict later.

Krzysztof

Ah, I only just applied this.

Can you rebase on my tree and resubmit please?

Don't worry about this. Andrew has a script to make them vanish if
applied elsewhere.
