Subject: NFC: st21nfcb: Remove inappropriate kfree on a previously devm_kzalloc pointer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=df2566fe37d92dfba032e6084ebfb708dac5dc9a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

NFC: st21nfcb: Remove inappropriate kfree on a previously devm_kzalloc pointer

In case of an error during driver probe, info pointer was freed with kfree.
No need to free anything when using devm_kzalloc.
