Subject: NFC: trf7970a: Remove useless local variable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=671970f531378e2a22ba0168d85dfca1f4e082c4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

NFC: trf7970a: Remove useless local variable

The trf7970a_suspend() routine always returns
zero so don't use a local return variable to
hold the return value.  This fixes up a smatch
warning.
