Subject: greybus: sdio: fix call to stop command if no data exist
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7a5cd5aea29a6fa0d99fb3b667b96b8d5f4e596c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

greybus: sdio: fix call to stop command if no data exist

If data is not available the stop command could dereference NULL.
Fetch the stop command directly from the request instead.
