Subject: [PATCH] PCI: qcom: Fix warning generated due to the incorrect data type
Date: Wed, 24 Nov 2021 19:34:24 +0530 [thread overview]
Message-ID: <20211124140424.51675-1-manivannan.sadhasivam@linaro.org> (raw)
Fix the below sparse warning due to the use of incorrect initializer
data type (u16) for bdf_be variable that receives the return value of
cpu_to_be16(). The correct type should be __be16.
sparse warnings: (new ones prefixed by >>)
