Subject: padata: add parenthesis in MAX_SEQ_NR macro
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=749d811f10a410b64cf4c674c498ec04316ec373;p=linux-beck.git

padata: add parenthesis in MAX_SEQ_NR macro

MAX_SEQ_NR is used in padata_alloc_pd() like this:

        pd->max_seq_nr = (MAX_SEQ_NR / num_cpus) * num_cpus - 1;

It needs parenthesis or the divide by num_cpus takes precedence over the
subtraction.
