Subject: extcon: palmas: Fix NULL pointer error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e350f8045f642dfc4c28a81c57d2103e1f7ceead;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

extcon: palmas: Fix NULL pointer error

This patch fixes NULL pointer error by removing the unneeded kfree() call
of edev->name because extcon-palmas no longer allocate the memory for edev->name.

Fixes: d71aadda19f8 ("extcon: Remove the optional name of extcon device")
