Subject: udf: Remove useless check in udf_adinicb_write_begin()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f27792f5b7e0ba8407fcdeabb5db778fe929ab78;p=linux-beck.git

udf: Remove useless check in udf_adinicb_write_begin()

As Al properly points out, len is guaranteed to be smaller than
PAGE_SIZE when we reach udf_adinicb_write_begin() as otherwise we would
have converted the file to the normal format.
