Subject: net: can: usb: ems_usb: don't print error when allocating urb fails
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=87ced2f9584efc476b955eb2343728fab20ff80b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: can: usb: ems_usb: don't print error when allocating urb fails

kmalloc will print enough information in case of failure.
