In __nfit_mem_init(), one nfit_mem will be created in case we can't find one nfit_mem with matched device_handle. The variable *found* indicates this research result. If we found one, variable *found* is set to non-NULL and variable *nfit_mem* already points to the data structure we want to set up. This is not necessary to reset variable *nfit_mem* to *found* again. This patch removes the assignment of *nfit_mem* to *found* when they are the same.
