Subject: ALSA: sparc: Add missing kfree in error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25e5eaf19962bd48788371e4f516bdd89ce248bc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ALSA: sparc: Add missing kfree in error path

If 'of_ioremap' fails, then 'amd' should be freed, otherwise, there is a
memory leak.
