Subject: [media] lm3560: prevent memory leak in case of pdata absence
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=341ef565f8287695709266e7533995ffcdcc7a38;p=linux-beck.git

[media] lm3560: prevent memory leak in case of pdata absence

If we have no pdata defined and driver fails to register we leak memory.
Converting to devm_kzalloc prevents this to happen.
