Subject: spi: oc-tiny: Use of_property_read_u32 instead of open-coding it
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=45a3e771085d16c95eb54f8009d795941b21fb28;p=linux-beck.git

spi: oc-tiny: Use of_property_read_u32 instead of open-coding it

Use of_property_read_u32 instead of of_get_property with return value
checks and endianness conversion.
