Subject: [PATCH V10 0/8] backlight: qcom-wled: Support for QCOM wled driver

This patch series renames the pm8941-wled.c driver to qcom-wled.c to add
the support for multiple PMICs supported by qualcomm. This patch series
supports both PM8941 and PMI8998 WLED. The PMI8998 WLED has the support
to handle the OVP (over voltage protection) and the SC (short circuit
protection)
interrupts. It also has the auto string detection algorithm support to
configure the right strings if the user specified string configuration
is in-correct. These three features are added in this series for PMI8998.
