Subject: lib/mpi: mpi_read_raw_data(): purge redundant clearing of nbits
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dfd90510672f69206942546e8df4f63cfa91eae6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

lib/mpi: mpi_read_raw_data(): purge redundant clearing of nbits

In mpi_read_raw_data(), unsigned nbits is calculated as follows:

 nbits = nbytes * 8;

and redundantly cleared later on if nbytes == 0:

  if (nbytes > 0)
    ...
  else
    nbits = 0;

Purge this redundant clearing for the sake of clarity.
