We let the callers pass the pointer to the buffer where the value of the Status Register will be written. This way we avoid the casts between int and u8, which can be confusing. Prepend spi_nor_ to the function name, all functions should begin with that. S/pr_err/dev_err and drop duplicated dev_err in callers, in case the function returns error.
