Commit a1f9b1c0439db ("integrity/ima: switch to using __kernel_read") replaced the __vfs_read() call in integrity_kernel_read() with __kernel_read(), a new helper introduced by commit 61a707c543e2a ("fs: add a __kernel_read helper").
Since the new helper requires that also the FMODE_CAN_READ flag is set in file->f_mode, this patch saves the original f_mode and sets the flag if the the file descriptor has the necessary file operation. Lastly, it restores the original f_mode at the end of ima_calc_file_hash().
